Exodus 7 is the chapter where the confrontation between Moses and Pharaoh turns from words into signs. God sends Moses and Aaron back to the king of Egypt with a command to release the Israelites, and the first plague, the Nile turned to blood, follows. People read Exodus 7 for its summary of how the plagues begin, for its unsettling note that Pharaoh’s heart is hardened, and for its clear message that the LORD intends to make himself known to Egypt and to Israel.
Exodus 7 Summary
The chapter opens with God commissioning Moses as a figure of divine authority before Pharaoh, with Aaron serving as his spokesman. Moses and Aaron go to the palace and perform a sign: Aaron’s staff becomes a serpent. Pharaoh summons his own wise men and sorcerers, who reproduce the act, but Aaron’s serpent swallows theirs. Pharaoh’s heart remains hard, and he refuses to listen, just as the LORD had said.
God then instructs Moses to meet Pharaoh at the river early in the morning and to announce the first plague. Aaron stretches his staff over the waters of Egypt, and the Nile and every pool, stream and vessel of water turn to blood. The fish die, the water stinks, and the Egyptians cannot drink it. The magicians copy the sign, Pharaoh again refuses to yield, and the chapter closes with a seven-day interval that marks the passing of the first plague.
Background and Setting
Exodus is the second book of the Torah, traditionally attributed to Moses, who is its central human figure. Most scholars date the events of the book to the late second millennium BC, though the exact Pharaoh and date are debated, and the book itself was shaped over a long period before reaching its present form. It was written and preserved first for the Israelite community, telling them where they came from and who the God who rescued them is.
Chapter 7 sits at the start of the plague narrative, which runs from here through chapter 12. Chapters 5 and 6 have already shown Pharaoh rejecting Moses’s first request and the people’s hardship increasing, so this chapter resets the story with a fresh divine commission and the first public sign against Egypt.
Exodus 7 Section by Section
Verses 1-7: The Prophet Sent Back to Pharaoh
1 The LORD said to Moses, “Behold, I have made you as God to Pharaoh; and Aaron your brother shall be your prophet. 2 You shall speak all that I command you; and Aaron your brother shall speak to Pharaoh, that he let the children of Israel go out of his land.
Exodus 7:1-2 (WEB)
God begins by telling Moses that he has been made “as God” to Pharaoh, and that Aaron will be his prophet. This reverses the fear and reluctance Moses expressed earlier. The authority does not come from Moses’s own eloquence but from the LORD who speaks through him. Moses is told to say all that God commands, and Aaron is the one who will carry those words to the king.
The section ends with a short note on the ages of the two brothers, eighty and eighty-three, and with the simple statement that they did as the LORD commanded. The narrative is quietly setting up the obedience that will follow in each scene.
Verses 8-13: The Serpent and the Sorcerers
10 Moses and Aaron went in to Pharaoh, and they did so, as the LORD had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent. 11 Then Pharaoh also called for the wise men and the sorcerers. They also, the magicians of Egypt, did the same thing with their enchantments. 12 For they each cast down their rods, and they became serpents: but Aaron’s rod swallowed up their rods.
Exodus 7:10-12 (WEB)
When Pharaoh asks for a miracle, God tells Moses to have Aaron cast down his staff, and it becomes a serpent. The Egyptian magicians do the same with their own enchantments, which shows that their arts can imitate the outward form of a sign. But Aaron’s staff swallows theirs, a picture of the LORD’s power overcoming the rival powers that Egypt relies on.
The section closes by noting that Pharaoh’s heart was hardened and that he did not listen, exactly as the LORD had said. The chapter is careful to show that Pharaoh’s refusal is part of a larger divine purpose and not a surprise to God.
Verses 14-18: The Warning at the River
15 Go to Pharaoh in the morning. Behold, he goes out to the water; and you shall stand by the river’s bank to meet him; and the rod which was turned to a serpent you shall take in your hand. 16 You shall tell him, ‘The LORD, the God of the Hebrews, has sent me to you, saying, “Let my people go, that they may serve me in the wilderness:” and behold, until now you haven’t listened. 17 The LORD says, “In this you shall know that I am the LORD. Behold, I will strike with the rod that is in my hand on the waters which are in the river, and they shall be turned to blood.
Exodus 7:15-17 (WEB)
God gives Moses precise instructions for the next confrontation. Pharaoh will go out to the water in the morning, and Moses is to stand on the riverbank with the staff in his hand. He is to deliver the message that the LORD, the God of the Hebrews, demands the release of the people so they may worship him in the wilderness.
The purpose is stated plainly: “In this you shall know that I am the LORD.” The plague that will follow is not only punishment but a revelation. Egypt will learn who the true God is through what happens to the very river that its religion and economy depend upon.
Verses 19-25: The Waters Turned to Blood
19 The LORD said to Moses, “Tell Aaron, ‘Take your rod, and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’” 20 Moses and Aaron did so, as the LORD commanded; and he lifted up the rod, and struck the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood. 21 The fish that were in the river died; and the river became foul, and the Egyptians couldn’t drink water from the river; and the blood was throughout all the land of Egypt.
Exodus 7:19-21 (WEB)
Aaron stretches out his staff over every body of water in Egypt, and all of it becomes blood, including the water stored in wooden and stone vessels. The fish die, the river becomes foul, and the people cannot drink from it. The plague is thorough and reaches far beyond the Nile itself.
The magicians again reproduce the effect, and Pharaoh’s heart remains hard. He turns and goes into his house without taking the matter to heart. The Egyptians dig beside the river for water, and the chapter ends with the note that seven days were fulfilled after the LORD struck the river. The passage shows how deep the disaster runs and how stubborn the king remains.
Key Themes in Exodus 7
- Divine authority: God gives Moses and Aaron their commission and their words, so their power comes from the LORD rather than from themselves.
- Hardened hearts: The chapter repeatedly says that Pharaoh’s heart is hard, which underlines that his refusal is both his own choice and part of God’s larger plan.
- Knowing the LORD: The plagues are meant to make God known to Egypt and to Israel, and the phrase “you shall know that I am the LORD” carries that purpose.
- Judgment on the gods of Egypt: The Nile was central to Egyptian religion and life, so turning it to blood confronts the power Egypt trusted.
Lessons From Exodus 7 for Today
Many people face a boss, a family member or a system that refuses to change, even after clear and repeated appeals. Exodus 7 shows that resistance is not the end of the story. Moses keeps going back to Pharaoh because God has sent him, and his faithfulness is measured by obedience rather than by immediate success.
The chapter also reminds readers that God is not caught off guard by hard situations. When a conversation seems hopeless or a decision feels stuck, the story invites trust that the LORD is still working through it. It does not promise that the other person will change at once, but it places the outcome in God’s hands.
Questions for Reflection
- Where in your life have you felt that you were speaking to someone who would not listen, and how did you respond?
- What does it mean to you that Moses’s authority came from God’s command rather than from his own confidence?
- How does the phrase “you shall know that I am the LORD” change the way you think about difficult seasons?
- What false sources of security, like the Nile for Egypt, might you be tempted to trust instead of God?
A Prayer From Exodus 7
Lord, you sent Moses and Aaron to speak your words even when the king would not listen, and you were faithful through every refusal. Help me to hear what you have asked of me and to obey without needing to see the result first. When I feel stuck in conversations or situations that seem unmovable, remind me that you are working and that you are making yourself known. Take away the things I have trusted more than you, and give me a steady heart that depends on you alone. Amen.
