The Law · Chapter 4 of 40

Exodus 4

Moses fears Israel will not believe him, so God gives three signs: a rod that becomes a serpent, a hand made leprous and healed, and water turned to blood. Moses pleads that he is not eloquent; God appoints Aaron as his mouth. Moses returns to Egypt with the rod of God. God warns Pharaoh's heart will be hardened. At an inn, a strange encounter over circumcision follows. Aaron meets Moses, and Israel believes.

What happens in Exodus 4

Moses objects that Israel will not believe the LORD appeared to him. God answers with three signs: his rod becomes a serpent and again a rod, his hand turns leprous and is healed, and, if needed, Nile water poured out will become blood. Still Moses protests that he is not eloquent but slow of speech. God reminds him who made the mouth and promises to be with his mouth. When Moses begs God to send someone else, God's anger is kindled, but He provides Aaron as spokesman, with Moses as God to him.

Moses takes leave of Jethro and returns to Egypt with the rod of God, warned that God will harden Pharaoh's heart and that Israel is God's firstborn son. On the way, at a lodging place, the LORD seeks to kill Moses, and Zipporah circumcises their son, calling Moses a bloody husband. Aaron meets Moses at the mount of God. Together they gather the elders, perform the signs, and the people believe and worship.

Exodus 4 in context

This scene concludes Moses's call, which began at the burning bush in the previous chapter, where God revealed His name and commissioned Moses to free Israel. Here Moses raises his final objections and God overrides them.

The mysterious circumcision episode underscores that even the deliverer must keep God's covenant. The chapter ends with Israel's initial belief, a fragile faith that Pharaoh's coming resistance will soon test.

Main themes of Exodus 4

God equips the reluctantMoses offers objection after objection, feeling unfit and unable. God does not choose him for his eloquence but promises to be with his mouth. The Lord supplies what the called one lacks, turning a stammering shepherd into His spokesman before the throne of Pharaoh.
Signs to awaken faithThe rod, the hand, and the water are given so Israel will believe God has truly appeared. God meets honest doubt with tangible confirmation, yet the signs point beyond themselves to the God who commands nature and keeps His covenant word to His people.
The covenant cannot be neglectedThe startling roadside episode shows that even Moses cannot ignore the sign of circumcision God required. Zipporah's swift act spares him. God's chosen servant is still bound to obey; deliverance does not exempt the deliverer from the covenant he carries.
This is part of the Law, the foundation of the whole story: creation, covenant, and a God who binds Himself to a people. As you read, watch for God's character and His promises, which all lead toward Christ.

Exodus 4 (KJV)

1And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The LORD hath not appeared unto thee. 2And the LORD said unto him, What is that in thine hand? And he said, A rod. 3And he said, Cast it on the ground. And he cast it on the ground, and it became a serpent; and Moses fled from before it. 4And the LORD said unto Moses, Put forth thine hand, and take it by the tail. And he put forth his hand, and caught it, and it became a rod in his hand: 5That they may believe that the LORD God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee. 6And the LORD said furthermore unto him, Put now thine hand into thy bosom. And he put his hand into his bosom: and when he took it out, behold, his hand was leprous as snow. 7And he said, Put thine hand into thy bosom again. And he put his hand into his bosom again; and plucked it out of his bosom, and, behold, it was turned again as his other flesh. 8And it shall come to pass, if they will not believe thee, neither hearken to the voice of the first sign, that they will believe the voice of the latter sign. 9And it shall come to pass, if they will not believe also these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river shall become blood upon the dry land. 10And Moses said unto the LORD, O my LORD, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue. 11And the LORD said unto him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD? 12Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say. 13And he said, O my LORD, send, I pray thee, by the hand of him whom thou wilt send. 14And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart. 15And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do. 16And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God. 17And thou shalt take this rod in thine hand, wherewith thou shalt do signs. 18And Moses went and returned to Jethro his father in law, and said unto him, Let me go, I pray thee, and return unto my brethren which are in Egypt, and see whether they be yet alive. And Jethro said to Moses, Go in peace. 19And the LORD said unto Moses in Midian, Go, return into Egypt: for all the men are dead which sought thy life. 20And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand. 21And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go. 22And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn: 23And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn. 24And it came to pass by the way in the inn, that the LORD met him, and sought to kill him. 25Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast it at his feet, and said, Surely a bloody husband art thou to me. 26So he let him go: then she said, A bloody husband thou art, because of the circumcision. 27And the LORD said to Aaron, Go into the wilderness to meet Moses. And he went, and met him in the mount of God, and kissed him. 28And Moses told Aaron all the words of the LORD who had sent him, and all the signs which he had commanded him. 29And Moses and Aaron went and gathered together all the elders of the children of Israel: 30And Aaron spake all the words which the LORD had spoken unto Moses, and did the signs in the sight of the people. 31And the people believed: and when they heard that the LORD had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped.

Verses to carry from Exodus 4

“And the LORD said unto him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?”Exodus 4:11

“Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.”Exodus 4:12

“And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn:”Exodus 4:22

Thematic connection

How Exodus 4 points to Jesus

God calls Israel my son, even my firstborn (Exodus 4:22), naming His people with a sonship that the New Testament gathers up in Jesus, the true firstborn Son who is called out of Egypt. Moses, the mediator who speaks God's words to the people and stands as God to Aaron, foreshadows the greater mediator, Christ, through whom God speaks His final word. The roadside scene, where blood shed in the covenant sign turns away death, faintly anticipates how blood will spare Israel at Passover and, in Christian reading, how Christ's blood turns aside judgment.

These are thematic connections rather than direct prophecies, yet the sonship of Israel and the mediating role of Moses both find their fullness in Jesus.

Questions about Exodus 4

Why was God angry when He had shown such patience with Moses?

God had answered every objection, promising His presence, His words, and confirming signs. When Moses still asked God to send someone else, it exposed not honest fear but reluctance to trust the God who was plainly with him. God's anger is real, yet even then He graciously provides Aaron. Patience has limits, but grace still prevails here.

What is happening in the strange episode about the bloody husband?

The account is compressed and difficult, but its point is clear: Moses had not circumcised his son, neglecting the covenant sign God gave Abraham. As Moses goes to demand covenant obedience from Pharaoh, his own household must be set right. Zipporah performs the circumcision, blood is applied, and Moses is spared. The covenant is not optional, even for the deliverer.

Reflection

Moses felt utterly unqualified, and God called him anyway, promising to be with his mouth. We often disqualify ourselves by looking at our weaknesses instead of God's presence. What has God asked of you that you have refused, feeling unable? His answer to Moses still stands: I will be with you.

A prayer from Exodus 4

Lord, I make excuses when You call, pointing to all I lack. Remind me that You made my mouth and go with me. Give me courage to obey, and keep my own house faithful to Your covenant even as I serve You. Amen.
