The Book of Exodus

Chapter 4: Signs and Excuses

Still standing at the burning bush, Moses keeps raising objections, and God keeps answering. God turns Moses' shepherd's rod into a serpent and back again, makes his hand leprous and heals it, all signs to prove the LORD has sent him. When Moses pleads that he is "slow of speech," God answers, "Who hath made man's mouth? ... I will be with thy mouth." At last Moses simply asks God to send someone else, and God, His anger kindled, appoints Aaron to speak for him. Moses returns to Egypt with the rod of God in his hand, carrying a message for Pharaoh: "Israel is my son, even my firstborn." Exodus 4 is a chapter about the God who equips those He calls, who will not accept our excuses, who loves His people as a Father, and who requires His servants to obey Him even in their own homes.

About This Commentary

This is a verse-by-verse study of Exodus chapter 4. For each section you will find the KJV text, the Hebrew words that sharpen the meaning, plain explanation, and a Gospel Focus. Chapter 4 is the rest of Moses' call: the signs God gives him, the excuses God answers, the appointing of Aaron, and Moses' return to Egypt. It teaches that God equips those He sends, and that He is a Father to His people. Every Scripture quotation is from the King James Version.

Setting the Stage

The Signs

The Rod in His Hand

God gives Moses three signs, the rod, the leprous hand, and water to blood, to prove that the LORD has truly appeared to him.

The Excuses

Who Made Man's Mouth?

Moses pleads that he cannot speak, and God answers that He made the mouth and will be with it, then appoints Aaron when Moses still shrinks back.

The Son

Israel My Firstborn

Returning to Egypt, Moses carries God's word to Pharaoh, calling Israel God's own son and firstborn, whom Pharaoh must let go.

The Covenant

Obedience at Home

A startling encounter at the inn shows that the deliverer himself must keep God's covenant in his own house before he leads the nation.

The Signs

What Is That in Thine Hand? (Exodus 4:1-9)

God answers Moses' fear that no one will believe him by giving three signs, beginning with the rod already in his hand.

Exodus 4:1-9

The Rod That Became a Serpent

"And 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. And the LORD said unto him, What is that in thine hand? And he said, A rod. And 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. And 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: That 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. And 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. And 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. And 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. And 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."

Hebrew Study

The three signs are lessons in God's use of the ordinary. The rod (matteh) — a plain shepherd's staff — becomes a serpent (nachash) and then a rod again in Moses' grip; the leprous hand is healed; Nile-water turns to blood. Each is given "that they may believe" — aman, the verb behind our word "amen," to hold firm as trustworthy. The power is never in the staff or the hand; it is in the God who bends the commonest things to His word once they are surrendered to Him.

Explanation

Moses fears the people will not believe that God appeared to him, so God gives him signs. He starts with a simple question: "What is that in thine hand?" It was only a shepherd's rod, an ordinary staff. God tells Moses to throw it down, and it becomes a serpent, so alarming that Moses flees from it. Then God tells him to pick it up by the tail, and it becomes a rod again. God gives two more signs: Moses' hand turns leprous when he puts it in his bosom, then is healed when he does it again, and water from the river will turn to blood on the ground. These signs are given so that "they may believe that the LORD God of their fathers ... hath appeared unto thee." God authenticates His messenger with evidence the people can see.

Gospel Focus

"What is that in thine hand?" God did not send Moses to find some new and impressive tool; He used the plain rod Moses already held. That ordinary shepherd's staff, surrendered to God, became "the rod of God" (verse 20) that would part the sea and strike the rock. This is how God works. He does not usually ask for what we do not have; He asks for what is already in our hand, and when we yield it to Him, He makes it mighty. Whatever you hold, your skill, your job, your voice, your small resources, lay it down before God and take it up again in His service, and He can do wonders with it. The same hand that could do nothing to free a nation became, in God's service, the instrument of the greatest deliverance in the Old Testament. Do not despise the ordinary thing in your hand; surrendered to God, it becomes extraordinary.

The Excuses

I Will Be With Thy Mouth (Exodus 4:10-17)

Moses protests that he cannot speak, and God answers that He made the mouth and will be with it, then in mercy appoints Aaron to help.

Exodus 4:10-21

Who Hath Made Man's Mouth?

"And 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. 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? Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say. And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send. And 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. And 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. And 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. And thou shalt take this rod in thine hand, wherewith thou shalt do signs. And 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. And the LORD said unto Moses in Midian, Go, return into Egypt: for all the men are dead which sought thy life. And 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. And 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."

Hebrew Study

Moses pleads that he is "slow of speech, and of a slow tongue" — kevad peh, "heavy of mouth." God's reply goes to the root: "Who hath made man's mouth?... have not I the LORD?" The Maker of the mouth undertakes to fill it — "I will be with thy mouth," ehyeh im-pikha, the very "I AM" (Ehyeh) just revealed at the bush, now pledged to a stammering tongue. Aaron is added as spokesman, "instead of a mouth," while Moses stands to him "instead of God" (le-Elohim) — the word carrying the authority of the One who sends.

Explanation

Moses raises his deepest objection: "I am not eloquent ... I am slow of speech, and of a slow tongue." He feels unqualified for the task because of his weakness in speaking. God's answer cuts to the root: "Who hath made man's mouth? ... have not I the LORD?" The God who made Moses' mouth, and who makes the deaf and the blind, is not limited by Moses' limitation. So God commands and promises together: "Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say." Yet Moses still shrinks back, finally asking God to "send ... by the hand of him whom thou wilt send," that is, send someone else. This kindles God's anger, and though He graciously appoints Aaron to be Moses' spokesman, it is a concession, not the first plan. Moses will still carry the rod and do the signs; God simply provides a mouth alongside him.

Gospel Focus

"Who hath made man's mouth?" is God's answer to every excuse of inadequacy. When God calls, He is not asking whether we are able; He is promising to make us able. The Maker of the mouth can surely fill it: "I will be with thy mouth, and teach thee what thou shalt say." Jesus gave His disciples the same promise for their hardest moments: "it is not ye that speak, but the Spirit of your Father which speaketh in you" (Matthew 10:20). Our weakness is no obstacle to God; it is His opportunity, for He told Paul, "My grace is sufficient for thee: for my strength is made perfect in weakness" (2 Corinthians 12:9). But there is a warning here too. God patiently answered every objection, but when Moses simply refused, asking Him to send another, God's anger was kindled. There is a difference between honest weakness, which God delights to strengthen, and unwilling excuse, which resists God's call. God can use the slow of speech; what He will not accept is a heart that will not go. When He calls, the answer is not "I cannot," but "here am I, send me."

The Son

Israel Is My Son, My Firstborn (Exodus 4:18-23)

Moses returns to Egypt with the rod of God, carrying a message that reveals God's fatherly love for His people.

Exodus 4:22-28

Let My Son Go, That He May Serve Me

"And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn: And 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. And it came to pass by the way in the inn, that the LORD met him, and sought to kill him. Then 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. So he let him go: then she said, A bloody husband thou art, because of the circumcision. And 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. And Moses told Aaron all the words of the LORD who had sent him, and all the signs which he had commanded him."

Hebrew Study

Here God names Israel with a startling tenderness: "Israel is my son, even my firstborn" — beni bekhori — a whole nation claimed as God's own son. And the aim of the exodus is stated for the first time: "let my son go, that he may serve me" (avad, to serve and to worship) — redemption is for worship, never merely from bondage. The warning that seals it is exact justice: if Pharaoh will not release God's firstborn son, "I will slay thy son, even thy firstborn" — son for son, the last plague already foretold.

Explanation

Moses gets Jethro's blessing, and God confirms that the men who sought his life are dead. So Moses sets his wife and sons on a donkey and returns to Egypt with "the rod of God in his hand." God warns Moses that Pharaoh's heart will be hard, but gives him the message to deliver: "Thus saith the LORD, Israel is my son, even my firstborn." This is the first time in the Bible God calls Israel His son. The demand follows: "Let my son go, that he may serve me," and the warning, that if Pharaoh refuses, God will take Pharaoh's own firstborn. The conflict is set as a matter between fathers and sons. Egypt held God's son in bondage; if Egypt would not release God's firstborn, Egypt's firstborn would fall. The whole struggle with Pharaoh is, at its heart, God reclaiming His son.

Gospel Focus

"Israel is my son, even my firstborn." God does not merely rule Israel as a king rules subjects; He loves them as a Father loves a son. That fatherly love is the reason for the whole Exodus: God is not only freeing slaves, He is bringing home His son. The prophet later looked back on this very deliverance and said, "When Israel was a child, then I loved him, and called my son out of Egypt" (Hosea 11:1). And the New Testament shows that this word reached its fullness in Christ, for Matthew tells us that when Jesus came up out of Egypt as a child, it fulfilled the saying, "Out of Egypt have I called my son" (Matthew 2:15). Israel the son was a shadow; Jesus is the true Son called out of Egypt. See also the purpose of the deliverance: "Let my son go, that he may serve me." God did not free Israel merely to be free, but to be His, to worship and serve Him. So it is with our redemption. Christ did not save us only from bondage but for God, that we, brought out of Egypt, might serve the Father who calls us His own.

The Covenant

A Bloody Husband, and a People Who Believed (Exodus 4:24-31)

A sobering encounter at the inn shows that the deliverer must keep God's covenant in his own house, and then Aaron meets Moses and the people believe.

Exodus 4:29-31

The People Believed and Worshipped

"And Moses and Aaron went and gathered together all the elders of the children of Israel: And Aaron spake all the words which the LORD had spoken unto Moses, and did the signs in the sight of the people. And 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."

Hebrew Study

The strangest scene in the chapter: on the way, "the LORD met him, and sought to kill him," until Zipporah circumcises their son and touches Moses' feet with the foreskin — "a bloody husband art thou," chatan damim, a bridegroom of blood. The lesson is severe: the man sent to lead a covenant people cannot despise the covenant sign in his own house. Blood applied turns death away — a Passover in miniature, long before the night of the lamb. Then the people, hearing that the LORD had visited them, "bowed their heads and worshipped" (shachah).

Explanation

On the way to Egypt comes one of the most startling passages in Exodus: "the LORD met him, and sought to kill him." Moses, God's chosen deliverer, had failed to circumcise his son, the sign of God's covenant with Abraham. Zipporah quickly circumcises the boy, and the danger passes. The details are brief and sobering, but the point is clear: the man God was sending to lead His covenant people could not himself neglect the covenant in his own family. Then the scene turns bright. God sends Aaron to meet Moses in the wilderness, and they embrace; Moses tells him all God has said. Together they gather the elders, Aaron speaks God's words and does the signs, "and the people believed." When Israel hears "that the LORD had visited" them and "looked upon their affliction," they bow their heads and worship. The long-awaited visitation has begun.

Gospel Focus

The encounter at the inn is a solemn reminder that God holds His servants to obedience in their own homes, not only in public. Moses was about to confront Pharaoh and lead a nation, yet God stopped him over an unkept covenant in his own family. The New Testament asks the same question of those who would lead God's people: "if a man know not how to rule his own house, how shall he take care of the church of God?" (1 Timothy 3:5). Private obedience must come before public ministry; God will not overlook at home what He calls us to teach abroad. And notice how the chapter ends: the people "believed ... and worshipped" when they heard that God had visited them. This is the answer to the promise that closed Genesis, "God will surely visit you." The God who remembers His covenant had begun to act, and the right response to His visitation is faith and worship. When we hear that God has seen our affliction and come to save, our hearts too should bow. The deliverance had not yet happened, but the people worshiped the God who had promised it, trusting the visitation that had only begun.

Chapter 4 in Review

Exodus 4 completes the call of Moses. God answers his fear that no one will believe by giving three signs, beginning with the ordinary rod in his hand. He answers Moses' plea that he cannot speak with "Who hath made man's mouth? ... I will be with thy mouth," and when Moses still asks Him to send another, God, His anger kindled, appoints Aaron. Moses returns to Egypt with the rod of God and God's message: "Israel is my son, even my firstborn ... let my son go, that he may serve me." At the inn God confronts Moses over his unkept covenant, and Zipporah circumcises their son. Then Aaron meets Moses, they gather the elders, and the people believe and worship when they hear that God has visited them.

For the Apostolic reader, this chapter teaches how God deals with those He calls. He uses what is already in our hand, surrendered to Him. He answers our excuses not by praising our ability but by promising His presence, for the Maker of the mouth will fill it, and His strength is made perfect in weakness. He loves His people as a Father, calling Israel His firstborn son, a shadow of the true Son called out of Egypt, Jesus. He frees His people not merely from bondage but for His service. And He requires His servants to obey Him at home before they lead abroad. The chapter ends where faith always begins, with a people who hear that God has visited them, and bow their heads to worship.

Key Takeaways
  • God uses what is already in your hand; surrendered to Him, the ordinary becomes the rod of God (4:2; 4:20).
  • God answers excuses with His presence: "Who hath made man's mouth? ... I will be with thy mouth" (4:11-12; Matthew 10:20).
  • Weakness is God's opportunity, but a heart that will not go kindles His anger (4:13-14; 2 Corinthians 12:9).
  • God loves His people as a Father; Israel the firstborn son foreshadows Christ called out of Egypt (4:22; Hosea 11:1; Matthew 2:15).
  • God requires obedience at home before public ministry (4:24-26; 1 Timothy 3:5).

Questions for Reflection

  • God asked, "What is that in thine hand?" What ordinary thing might God be asking you to surrender for His use?
  • Moses pleaded his weakness; God promised His presence. Where are you disqualifying yourself when God is offering to be with your mouth?
  • God stopped Moses over obedience at home. Is there something in your own house God is asking you to set right?
