Context

By the end of chapter 3, God had already told Moses his mission and plan in detail. Chapter 4 is an entire chapter of Moses continuing to make excuses—he offers three reasons to refuse, God responds with three replies or signs, and finally God's anger burns and He appoints Aaron to go along. This chapter reveals the true inner state of the one who is called, and the deep patience of God.

Passage Structure

Key Verses of This Chapter

“Yahweh’s anger burned against Moses, and he said, “What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he is coming out to meet you. When he sees you, he will be glad in his heart.” (4:14)

“The people believed, and when they heard that Yahweh had visited the children of Israel, and that he had seen their affliction, then they bowed their heads and worshiped.” (4:31)

Core Message of the Chapter

Being called is not "a perfectly equipped hero being sent out." Being called is a real, reluctant, help-needing person being patiently brought to his post by God. God's patience has a boundary—He does grow angry (4:14)—but His grace is wider than that boundary. He will give you an Aaron, perform three signs, and in the end bring the people to bow in worship. God does not abandon those He calls.

A Pastoral Word

Dear brothers and sisters,

If you are reading Exodus chapter 4 today and you see Moses making four excuses to refuse, you may find it strangely familiar—because this is what every person called by God actually looks like.

We tend to assume that those who are called are saints with "great spirituality, eloquent speech, and strong faith." But Scripture records Moses' most unvarnished state: eighty years old, making excuses, claiming he cannot speak, and finally just saying, "Please send someone else." God did not airbrush Moses into a stained-glass portrait. He lets us see a struggling, unwilling, excuse-making man who is slowly brought to his post.

Notice: God did not give up on him. From "Who am I?" in 3:11 to "Please send someone else" in 4:13, every time Moses offered an excuse, God answered with a promise. Then in 4:14 God's anger burned—but what followed the anger was not punishment; it was Aaron. God's anger operates within a framework of grace. He adjusts the instrument, but He does not cancel the mission.

If you are standing today at some edge of "I can't do this"—a ministry role, a relationship, a responsibility, a new season of life—hear the two things God said to Moses:

  1. "Who made man's mouth?" (4:11). Whatever you think you lack, can the God who made you not supply it?
  2. "I will be with your mouth." (4:12). "I will be" — ehyeh — the same "I AM" who causes things to come to pass.

This self-existent, eternal God can turn a shepherd's staff into "the staff of God," and turn an eighty-year-old, slow-tongued fugitive into the leader of two million people. He can make your ordinary "staff" a vessel for His glory.

Finally, look at 4:31: Israel bowed their heads and worshiped. Moses had worried all the way from Sinai—"They won't believe me"—yet when he arrived in Egypt, the people believed immediately and worshiped immediately. God had told Moses beforehand, "They will listen to you," and Moses had not believed it. Many of the things you are anxious about today may already be settled in God's hands. Let go—not letting go of the doing, but releasing your grip on anxiety over the outcome.

Reflection Questions

  1. Moses used four excuses: unbelief, poor speech, "send someone else," and a hidden "I simply don't want to." Are you currently using some excuse to avoid a calling that God has made clear in your heart? Bring it into prayer and name it plainly—don't dress it up.

  2. 4:11 — "Who made man's mouth?" Bring your deepest "I don't have what it takes" before this verse. The God who made you knows your inadequacy. Can He supply what is lacking?

  3. 4:24–26 — On the very road to deliver others, Moses nearly lost his life because he had not circumcised his own son. In your ministry, is there a blind spot where you are laboring hard for others while neglecting a basic covenant obligation in your own household?

I. Objection 2 + Three Signs (4:1-9)

Positioning This Passage

At the end of chapter 3, God answered Moses' two objections (verse 11: "Who am I?" and verse 13: "What is your name?"). Chapter 4 opens with yet another objection: "They won't believe me." This is Moses' third excuse (3:11; 3:13; 4:1), and it is the narrator's deliberate highlighting of "the called one's inner resistance."

4:1 "Moses answered, “But, behold, they will not believe me, nor listen to my voice; for they will say, ‘Yahweh has not appeared to you.’”"

Exodus 4:1(World English Bible)

Moses' concern is entirely understandable. He had been away from Egypt for forty years — who would still remember him? And now he was going back to say "Yahweh appeared to me." On whose authority should anyone believe the word of an outsider?

But notice: God had already personally promised in 3:18, "They will listen to your voice." Moses is refusing to trust that promise. This is the essence of unbelief — doubting God's assurance and placing "rational anxiety" above "God's word."

4:2-4 "Yahweh said to him, “What is that in your hand?” He said, “A rod.” He said, “Throw it on the ground.” He threw it on the ground, and it became a snake; and Moses ran away from it. Yahweh said to Moses, “Stretch out your hand, and take it by the tail.” He stretched out his hand, and took hold of it, and it became a rod in his hand."

Exodus 4:2-4(World English Bible)

The design of the first sign is rich with teaching significance:

4:6-7 "Yahweh said furthermore to him, “Now put your hand inside your cloak.” He put his hand inside his cloak, and when he took it out, behold, his hand was leprous, as white as snow. He said, “Put your hand inside your cloak again.” He put his hand inside his cloak again, and when he took it out of his cloak, behold, it had turned again as his other flesh."

Exodus 4:6-7(World English Bible)

Leprosy (צָרַעַת, tsara'at): in ancient Near Eastern culture, leprosy was virtually a death sentence. In Scripture it is also the most severe form of ritual uncleanness (Leviticus 13–14).

The theology of the second sign: God can turn the cleanest thing (Moses' hand) into the most unclean, and can restore the most unclean in an instant. This previews God's power to cleanse — the power to cleanse anyone. It is also a warning: he can judge, and he can save.

Placing the hand "inside your cloak" (חֵיק, cheyq, "bosom/chest"): God's power comes through intimate contact, not remote-control magic.

4:8-9 "“It will happen, if they will not believe you or listen to the voice of the first sign, that they will believe the voice of the latter sign. It will happen, if they will not believe even these two signs or listen to your voice, that you shall take of the water of the river, and pour it on the dry land. The water which you take out of the river will become blood on the dry land.”"

Exodus 4:8-9(World English Bible)

The third sign is not demonstrated on the spot — it is held in reserve for Moses. It is a preview for Pharaoh: the Nile turning to blood (7:14-25, the first plague). The narrator plants the seed of the ten plagues as early as chapter 4: the third sign is a dress rehearsal for the first plague.

Notice the patient structure God builds: believe one → believe two → if you still won't believe, here is a third. God provides more evidence than our unbelief requires. This is grace as pedagogy.

II. Objection 3: Slow of Speech (4:10-12)

4:10 "Moses said to Yahweh, “O Lord, I am not eloquent, neither before now, nor since you have spoken to your servant; for I am slow of speech, and of a slow tongue.”"

Exodus 4:10(World English Bible)

Moses' fourth excuse: eloquence. The Hebrew כְבַד-פֶּה וּכְבַד לָשׁוֹן (kvad-peh u-kvad lashon, "heavy of mouth and heavy of tongue") may describe a genuine speech difficulty (a stutter?), or it may be an excuse — after all, Moses had received a full education in Pharaoh's palace.

Whether genuine or not, Moses' hidden problem is not his speech; it is his unwillingness to go. Every excuse is a different wrapping around the same real issue: "I don't want to go." This is what the narrator wants us to see.

"Neither before now, nor since you have spoken to your servant" is a telling phrase. Moses is implying, "Even after you just spoke to me, I haven't improved" — he doubts that God can change him. This is a form of covert unbelief.

4:11-12 "Yahweh said to him, “Who made man’s mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn’t it I, Yahweh? Now therefore go, and I will be with your mouth, and teach you what you shall speak.”"

Exodus 4:11-12(World English Bible)

God's answer is an eruption of creation theology: "Who made man's mouth?" God first lifts Moses from "I have no eloquence" to "Who is the maker of eloquence?" If God made the mouth, he can repair the mouth — and he can speak through any mouth.

At a deeper level: the maker of mouths can use any mouth he chooses. God spoke through a donkey (Numbers 22:28), through a fisherman (Peter at Pentecost), through a tax collector (Matthew). He uses the "unlikely" to proclaim his word.

"I will be with your mouth" — the Hebrew is אָנֹכִי אֶהְיֶה עִם-פִּיךָ (anokhi ehyeh im-pikha, "I myself will be with your mouth"). This is ehyeh appearing for the third time (3:12 "I will be with you"; 3:14 "I AM WHO I AM"; 4:12 "I will be with your mouth"). God's presence becomes concrete — reaching down to the mouth, the tongue, the very words.

III. Objection 4: Please Send Someone Else (4:13-17)

4:13 "He said, “Oh, Lord, please send someone else.”"

Exodus 4:13(World English Bible)

This is Moses' final card. With every excuse refuted, he simply says it plainly: "Not me."

The Hebrew שְׁלַח-נָא בְּיַד-תִּשְׁלָח (shlach-na be-yad-tishlach, "please send by the hand of whomever you will send") is deliberately vague — it may mean: "Send someone who is actually suited for this."

This is the narrative's point of highest tension. Moses is no longer pretending to be worried; he admits: I do not want to go.

4:14 "Yahweh’s anger burned against Moses, and he said, “What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he comes out to meet you. When he sees you, he will be glad in his heart."

Exodus 4:14(World English Bible)

"Yahweh's anger burned" — this is the first time in Exodus that God's anger is directed at Moses personally. God's patience has a boundary.

But notice what the anger actually produces: God does not cancel Moses' calling, does not punish him, does not threaten him. He simply says, "Then your brother will go with you." God's anger operates within a framework of grace — he adjusts the instrument without cancelling the mission.

Aaron is mentioned here for the first time in the narrative. He will later become the first high priest (Exodus 28–29). Moses' resistance actually triggers God's provision of a priestly family: Israel will have not only a prophet (Moses) but also a priest (Aaron). God can even use human weakness to advance his multifaceted design.

"He comes out to meet you" — God announces: while you are still at Sinai, Aaron is already on the road. God's preparation precedes human response.

4:15-17 "You shall speak to him, and put the words in his mouth. I will be with your mouth, and with his mouth, and will teach you what you shall do. He will be your spokesman to the people; and it will happen, that he will be to you a mouth, and you will be to him as God. You shall take this rod in your hand, with which you shall do the signs.”"

Exodus 4:15-17(World English Bible)

Aaron serves as Moses' "mouth"; Moses serves as Aaron's "God." The Hebrew לֵאלֹהִים (l'Elohim, "as God") means Moses relays God's words to Aaron as God does to a prophet, and Aaron in turn speaks to the people as a prophet. This is an early prototype of the prophet–priest model God is designing.

The staff — the instrument of the first sign — is reaffirmed here. Moses' staff will later part the Red Sea (chapter 14), strike the rock (chapter 17), and be raised during the battle against Amalek. This ordinary shepherd's crook will become the vessel of God's glory.

IV. Farewell to His Father-in-Law and the Return Journey (4:18-20)

4:18-20 "Moses went and returned to Jethro his father-in-law, and said to him, “Please let me go and return to my brothers who are in Egypt, and see whether they are still alive.” Jethro said to Moses, “Go in peace.” Yahweh said to Moses in Midian, “Go, return into Egypt; for all the men who sought your life are dead.” Moses took his wife and his sons, and set them on a donkey, and he returned to the land of Egypt. Moses took God’s rod in his hand."

Exodus 4:18-20(World English Bible)

Notice the end of verse 20: "God's staff." Earlier it was "Moses' staff" (4:2); now it is "God's staff." The same piece of wood, because it has been taken up by God, has become a sacred instrument.

"His sons" — besides Gershom (2:22), there is also Eliezer (18:4, "My father's God was my help"). The narrator mentions two sons here for the first time, laying the groundwork for their reunion with Zipporah in chapter 18.

V. God's Final Charge: Firstborn for Firstborn (4:21-23)

4:21-23 "Yahweh said to Moses, “When you go back into Egypt, see that you do before Pharaoh all the wonders which I have put in your hand, but I will harden his heart and he will not let the people go. You shall tell Pharaoh, ‘Yahweh says, Israel is my son, my firstborn, and I have said to you, “Let my son go, that he may serve me”; and you have refused to let him go. Behold, I will kill your son, your firstborn.’”"

Exodus 4:21-23(World English Bible)

This is one of the weightiest theological declarations in Exodus.

"Israel is my son, my firstborn" — Hebrew בְּנִי בְכֹרִי (beni bekhori, "my son, my firstborn"). In a patriarchal society, the firstborn was the heir of the estate and the bearer of the family's honour. God formally adopts Israel as his firstborn. From this moment, the entire Exodus narrative becomes a family matter: Pharaoh is not merely opposing a nation — he is opposing the firstborn son of God.

"I will harden his heart" — this is the first time in Exodus that God is said to actively harden Pharaoh's heart. But note the timing: this is chapter 4, a preview. In practice, through the first five plagues Pharaoh hardens his own heart (7:13, 22; 8:15, 19, 32; 9:7), and God allows him to harden it to the end. This is the complex theology of foreknowledge and responsibility (see the theological deep-dive in chapter 3).

"I will kill your son, your firstborn" — this previews the tenth plague. The climax of the entire book of Exodus is announced already in chapter 4: if you will not release my firstborn, I will take yours.

VI. The Crisis on the Road: The Night of Circumcision (4:24-26)

This is the most mysterious passage in the entire chapter — and arguably in the whole Old Testament.

4:24-26 "On the way at a lodging place, Yahweh met Moses and wanted to kill him. Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, “Surely you are a bridegroom of blood to me.” So he let him alone. Then she said, “You are a bridegroom of blood,” because of the circumcision."

Exodus 4:24-26(World English Bible)

Why is this passage so mysterious?

  1. God has just commissioned Moses — so why does he now seek to kill him?
  2. How did Zipporah know that circumcision was the answer?
  3. What does "bridegroom of blood" mean?
  4. When she "cast it at his feet," is "feet" a euphemism for genitals?

The most widely accepted interpretation:

Theological takeaways:

  1. God's calling does not exempt one from the demands of obedience. Being sent does not mean you may neglect the basic requirements of the covenant.
  2. A woman is once again the rescuer. Shiphrah, Puah, Moses' mother, his sister, Pharaoh's daughter, Zipporah — the chain of deliverance in Exodus is full of women.
  3. Blood is the sign of the covenant. This foreshadows the blood of the Passover in chapter 12 and the blood of the covenant ratification in chapter 24. "Blood saves life" is a thread running throughout Exodus.

After this episode, Zipporah and the children were apparently sent back to Midian (18:2: "after he had sent her away"), and Moses continued alone. This also explains why Jethro brings her back in chapter 18.

VII. Aaron Joins the Mission + The People Believe (4:27-31)

4:27-28 "Yahweh said to Aaron, “Go into the wilderness to meet Moses.” He went, and met him on God’s mountain, and kissed him. Moses told Aaron all Yahweh’s words with which he had sent him, and all the signs with which he had instructed him."

Exodus 4:27-28(World English Bible)

Aaron appears in verse 27, confirming God's announcement in 4:14. The two brothers had been separated for decades (Aaron was three years older than Moses; Exodus 7:7), and their first reunion takes place at Mount Horeb.

"On God's mountain" — the phrase appears again, signalling to the reader: this place will be seen again before long.

4:29-31 "Moses and Aaron went and gathered together all the elders of the children of Israel. Aaron spoke all the words which Yahweh had spoken to Moses, and did the signs in the sight of the people. The people believed, and when they heard that Yahweh had visited the children of Israel, and that he had seen their affliction, then they bowed their heads and worshiped."

Exodus 4:29-31(World English Bible)

"The people believed" — this is the complete reversal of Moses' fear in 4:1! Moses predicted "they will not believe me," yet they believed immediately. God's promise (3:18: "They will listen to your voice") was fulfilled. Moses' anxiety was unnecessary.

"They bowed their heads and worshiped" — Hebrew וַיִּקְּדוּ וַיִּשְׁתַּחֲווּ (va-yiqqedu va-yishtachavu, "they bowed down and prostrated themselves"). This is the first scene in Exodus of Israel worshipping Yahweh. Worship begins with belief, and belief begins with hearing that God has seen their suffering.

But note: this moment of faith will be shattered by the disappointment of chapter 5. The spiritual journey in Exodus is not a straight line — it moves from faith → disappointment → renewed faith → renewed disappointment → ultimate victory. This is the authentic shape of the spiritual life.

Why This Chapter Matters

Chapter 4 carries the call from the burning bush into the reality of execution. Moses' questions are no longer only "Who is God?" but also "Will people believe me?", "Can I even speak?", and "Can I just not go?" God answers each one — yet the reader also sees that a calling is not psychological reassurance; it is an entry into covenantal obedience. The three signs, Aaron as spokesman, the night of circumcision, and the people's belief together trace a path from resistance to action.

The chapter also brings the theme of "the firstborn" to the foreground. Israel is God's firstborn; if Pharaoh refuses to release him, he will face the judgment of the firstborn. The circumcision crisis in Moses' own household makes the same point from another angle: the one who carries the covenant must himself stand within the covenant. This lays the groundwork for the firstborn, the Passover, and the consecration of the firstborn in chapters 11–13.

Chapter Summary: God Accommodates Weakness but Does Not Indulge Avoidance

Chapter 4 portrays Moses with striking honesty. He is neither completely faithless nor fully prepared. He receives signs and continues to object; he fears his own inadequacy and yet God arranges for Aaron to accompany him. God provides evidence, a companion, and words — and also deals seriously with the crisis of the circumcision night. The text holds two truths together: God knows human weakness and therefore supplies help; God also takes his covenant seriously and therefore does not allow the one he sends to treat obedience lightly.

This has direct implications for ministry in the church. Some people need to be comforted, because they genuinely feel they are not articulate enough, not brave enough, not experienced enough. Others need to be gently challenged, because "I can't do it" can quietly become a spiritual justification for evading a calling. God did not require Moses to become a different person — he required Moses to obey with the limitations he had. Mature pastoral care should do the same: neither crush the fragile nor allow prolonged avoidance to be dressed up as humility.

Weakness Needs a Companion; Avoidance Needs to Be Lovingly Interrupted

Moses' "slow of speech and of a slow tongue" resonates deeply with many believers. Some people do not lack love for God — they have simply been weighed down for years by low self-worth, experiences of failure, language barriers, cultural displacement, or past trauma. The moment they think about speaking up, leading, or bearing witness, they see only their own inadequacy. God gave Moses Aaron not to shame him but to give him a fellow traveller. The church should learn to accompany people in the same way: not pushing someone forward with a quick "just have faith," but placing a companion alongside them in their genuine weakness.

Yet this chapter also reminds us that weakness cannot permanently serve as a reason to refuse obedience. God was willing to accommodate Moses, but he also grew angry at Moses' evasion; he arranged for Aaron, but he did not cancel Moses' commission. Healthy pastoral care must do two things at once: relieve people of unnecessary pressure born of weakness, and help them discern when "I can't" has quietly become "I won't trust." Grace does not leave people where they are — it holds them up and walks them forward.

Position Within the Book's Main Storyline

Chapter 4 connects the divine-name revelation of chapter 3 to the direct confrontation with Pharaoh in chapter 5. Without this chapter, Moses would seem to move straight from the burning bush to public leadership; with it, readers see how God patiently handles human excuses and how seriously He treats the sign of the covenant. God rescues His people not by bypassing weak vessels, but by displaying His sovereignty through them.

Application for the Church in Context

In multilingual, multicultural, and immigrant church settings, many people can identify with Moses's claim that he "cannot speak." Imperfect language fluency, slow verbal expression, and unfamiliarity with the surrounding culture often make people feel unfit for ministry. Exodus 4 reminds us that God can work through human limitations and can also arrange companions to supply what one person lacks. A church that only deploys its most articulate members or those who best fit the dominant culture will miss many of the Moseses whom God has called.

Weakness Is Met with Compassion, Avoidance Is Addressed

The pastoral tension in chapter 4 is subtle: God meets Moses's fear with compassion, giving him signs, a staff, a companion, and words to speak—yet God does not indulge Moses in hiding indefinitely behind "I can't do this." Weakness may be brought before God; avoidance, however, cannot be spiritualized away. Many who serve need neither to be pushed relentlessly nor to be left entirely to themselves, but to be re-commissioned within God's patience.

This chapter also lays the groundwork for the firstborn theme that runs through the rest of Exodus. The declaration in 4:22–23 that Israel is God's firstborn gives the Passover judgment on the firstborn its full theological weight. God does not send plagues arbitrarily; He is responding to Pharaoh's oppression of His firstborn son. Readers who trace this thread in chapter 4 will find the judgment and substitutionary redemption of chapters 11–12 far clearer.

Structural Diagram of Objections and Responses

The structure of the entire chapter is a progressive objection–response dialogue:

Objection 1 (3:11)  Who am I?                  →  I will be with you
Objection 2 (3:13)  What is your name?          →  I AM WHO I AM
Objection 3 (4:1)   They won't believe me       →  Three signs (staff/snake, leprosy, water/blood)
Objection 4 (4:10)  I am slow of speech         →  The God who made mouths will give you words

                                                 Fruit of obedience (4:31, the people believe and worship)

This is the classic biblical call-narrative pattern, seen later in varied forms in Gideon (Judges 6), Saul (1 Samuel 9–10), Jeremiah (Jeremiah 1), Mary (Luke 1), and Paul (Acts 9).

Ancient Near Eastern Background

The "Display of Signs" Tradition in the Ancient Near East

In the ancient Near East, signs were the means by which foreign deities demonstrated their power. Egyptian sorcerers could use their arts to turn staffs into snakes (Exodus 7:11) and to turn water into blood. Moses's staff-to-snake sign would therefore not immediately persuade Pharaoh — he knew his sorcerers could do the same.

Yet 7:12 reveals the decisive difference: Moses's staff swallowed the sorcerers' staffs. This is the spiritual truth: human sorcery can imitate the surface; it cannot imitate the power.

The Significance of Circumcision in the Ancient Near East

Circumcision (מִילָה, milah) was not unique to Israel. Egypt, Arabia, Canaan, and Phoenicia all had circumcision traditions. But Israel's circumcision had several distinctive features:

Ancient Near East Israel
Typically at puberty or before marriage On the eighth day after birth (Genesis 17:12)
Cultural marker Covenant marker
Certain groups (e.g., priests) All males

The circumcision of the Abrahamic covenant was the visible sign of the covenant; to refuse circumcision was to refuse the covenant. This is why Moses's failure to circumcise his son in 4:24 was so serious — he was about to lead the covenant people, yet he himself had not fulfilled the covenant's sign.

The Tradition of the Midianite Priest

As the daughter of a Midianite priest, Zipporah may have been unfamiliar with — or resistant to — Israel's circumcision tradition. Archaeological evidence suggests the Midianites had a "blood rite" tradition involving the application of blood to a bridegroom at a wedding. The phrase "bridegroom of blood" (chatan-damim) may draw on that Midianite tradition; Zipporah may have been expressing her complex emotions about the event in language drawn from her own background.

Tracking Theological Themes

1. The Purpose of Signs: Evidence vs. Control

In Exodus, signs have two categories of audience:

Sign Purpose Audience
4:2–9, three signs To cause Israel to believe Fellow Israelites
Chapters 7–12, ten plagues To make Pharaoh submit + to strengthen Israel + to make Egypt know Yahweh Enemy + fellow Israelites + the nations
Chapter 14, crossing the Red Sea Salvation God's people
Chapter 16, manna Provision The people in the wilderness

Signs are not for control; they are for revelation and redemption. The theology of signs in Exodus: signs are the fingerprint of God's sovereignty, not instruments by which humans control God.

2. "The Mouth" — A Key Body Part in Exodus

Notice the concentrated focus on "the mouth" in chapter 4:

In the Hebrew Bible, "the mouth" is far more than a speech organ. It is the outlet of the heart ("out of the abundance of the heart the mouth speaks"), the instrument of the prophet ("the word of Yahweh came to my mouth"), and the organ of worship ("my mouth will praise Yahweh").

The central conflict of Exodus is precisely "whose mouth has the final word" — Pharaoh's mouth versus Yahweh's mouth. Yahweh's mouth is the one that holds ultimate sovereignty.

3. Firstborn Theology: From Exodus 4:22 to Romans 8:29

"Israel is my firstborn son" (4:22) is the origin of firstborn theology in Scripture. This thread develops as follows:

Exodus 4:22      Israel is God's firstborn
Exodus 13:2      Every firstborn of Israel belongs to Yahweh
Psalm 89:27      God appoints David as firstborn
Luke 2:7         Mary gave birth to her firstborn son — Jesus
Romans 8:29      His Son is the firstborn among many brothers
Colossians 1:15  Christ is the firstborn of all creation
Hebrews 1:6      When God brings the firstborn into the world…
Revelation 1:5   The firstborn from the dead

The firstborn is the first, the set-apart, the one who receives a double portion of the inheritance, the one who bears the family's responsibility, the one under God's special care. The declaration in Exodus — "Israel is my firstborn" — finds its complete fulfillment in Christ, who is the ultimate Firstborn.

4:1 They won't believe me John 1:11 "He came to his own, and those who were his own didn't receive him." Christ's own people also largely rejected him
4:2–4 Staff becomes snake Matthew 10:16 "“Behold, I send you out as sheep among wolves. Therefore be wise as serpents and harmless as doves." The spiritual significance of the serpent is complex — both venomous and capable of being subdued
4:6–7 Cleansing of leprosy Matthew 8:1–3 The Lord Jesus touched the man with leprosy and immediately cleansed him The ultimate display of God's power to make clean
4:10–12 Slow of speech → God gives words Luke 12:11–12 "When they bring you before the synagogues, the rulers, and the authorities, don’t be anxious how or what you will answer or what you will say; > † 12:5 or, Hell ‡ 12:6 An assarion was a small copper coin worth about an hour’s wages for an agricultural laborer. § 12:25 A cubit is the length from the tip of the middle finger to the elbow on a man’s arm, or about" The Holy Spirit is the New Testament's "I will be with your mouth"
4:11 Who made the mouth/eyes John 9 — the Lord Jesus heals the man born blind, proving he is the one who made eyes The Creator comes to restore everything he made
4:14 God's anger, then Aaron given 1 Corinthians 12:21 "The eye can't tell the hand, 'I have no need of you.'" The necessity of co-workers; the diversity of the body
4:16 Aaron as Moses's mouth 2 Corinthians 5:20 "We are therefore ambassadors on behalf of Christ, as though God were entreating by us." We are Christ's "mouth," conveying his words
4:22 Israel my firstborn Romans 8:29; Colossians 1:15 — Christ is the Firstborn Firstborn theology runs through both Testaments
4:23 Refuse to release firstborn → kill firstborn John 3:16; Romans 8:32 "He who didn’t spare his own Son, but delivered him up for us all, how would he not also with him freely give us all things?" The irony: Pharaoh's refusal to release Israel's firstborn led to the death of Egypt's firstborn; God gave up his own Son to save our sons
4:24–26 Blood rite saves Moses Hebrews 9:22 "According to the law, nearly everything is cleansed with blood, and apart from shedding of blood there is no remission." The theme of blood-redemption runs throughout
4:31 The people bowed and worshiped Revelation 5:8–14 All creation worships the Lamb Recognition of redemption gives rise to worship

Stephen's comment in Acts 7:35 on Moses: "He said, “Who made you a prince and a judge over us? Do you plan to kill me, as you killed the Egyptian?” Moses was afraid, and said, “Surely this thing is known.”" The ironically dismissive question of Exodus 2:14 is answered by God himself in Exodus 4: "I appointed you." What people reject, God establishes — this is a type of Christ.
