Short answer: Exodus 7 records God's commission to Moses as 'God to Pharaoh,' the sign of the staff becoming a serpent before Pharaoh, the hardening of Pharaoh's heart, and the first plague of water turned to blood. The chapter begins the great contest between Yahweh and the gods of Egypt.
Introduction
Exodus 7 is a foundational chapter in the book of Exodus, situated within the larger narrative of God's redemption of Israel from Egypt and His establishment of the covenant at Sinai. This study guide provides a thorough examination of the chapter's content, themes, and theological significance, drawing exclusively from the World English Bible (WEB) translation.
Moses Appointed as God to Pharaoh (7:1-7)
God tells Moses that he will be as God to Pharaoh, with Aaron as his prophet. They are to speak all that God commands, though God will harden Pharaoh's heart. The signs and wonders will multiply so that Egypt will know that Yahweh is God. Moses is eighty years old, and Aaron eighty-three, when they speak to Pharaoh.
The Staff Becomes a Serpent (7:8-13)
When Pharaoh demands a sign, Aaron casts down his staff, and it becomes a serpent. Egypt's magicians replicate the sign, but Aaron's staff swallows theirs. Yet Pharaoh's heart is hardened, and he refuses to listen, just as God had said.
The First Plague: Water Turned to Blood (7:14-25)
God instructs Moses to meet Pharaoh at the Nile and warn him. When Pharaoh refuses, Aaron strikes the water, and the Nile turns to blood. The fish die, the river stinks, and the Egyptians cannot drink. The magicians replicate the plague, and Pharaoh's heart remains hard. The Egyptians dig around the Nile for drinking water.
Yahweh said to Moses, “Behold, I have made you as God to Pharaoh; and Aaron your brother shall be your prophet. 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. I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt. But Pharaoh will not listen to you, so I will lay my hand on Egypt, and bring out my armies, my people the children of Israel, out of the land of Egypt by great judgments. The Egyptians shall know that I am Yahweh when I stretch out my hand on Egypt, and bring the children of Israel out from among them.” Moses and Aaron did so. As Yahweh commanded them, so they did. Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
Exodus 7:1-7 (World English Bible)
Yahweh spoke to Moses and to Aaron, saying, “When Pharaoh speaks to you, saying, ‘Perform a miracle!’ then you shall tell Aaron, ‘Take your rod, and cast it down before Pharaoh, and it will become a serpent.’ ” Moses and Aaron went in to Pharaoh, and they did so, as Yahweh had commanded. Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent. Then Pharaoh also called for the wise men and the sorcerers. They also, the magicians of Egypt, did the same thing with their enchantments. For they each cast down their rods, and they became serpents; but Aaron’s rod swallowed up their rods. Pharaoh’s heart was hardened, and he didn’t listen to them, as Yahweh had spoken.
Exodus 7:8-13 (World English Bible)
Yahweh said to Moses, “Pharaoh’s heart is stubborn. He refuses to let the people go. Go to Pharaoh in the morning. Behold, he is going out to the water. You shall stand by the river’s bank to meet him. You shall take the rod which was turned to a serpent in your hand. You shall tell him, ‘Yahweh, the God of the Hebrews, has sent me to you, saying, “Let my people go, that they may serve me in the wilderness. Behold, until now you haven’t listened.” Yahweh says, “In this you shall know that I am Yahweh. 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. The fish that are in the river will die and the river will become foul. The Egyptians will loathe to drink water from the river.” ’ ” Yahweh 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. There will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’ ” Moses and Aaron did so, as Yahweh 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. The fish that were in the river died. The river became foul. The Egyptians couldn’t drink water from the river. The blood was throughout all the land of Egypt. The magicians of Egypt did the same thing with their enchantments. So Pharaoh’s heart was hardened, and he didn’t listen to them, as Yahweh had spoken. Pharaoh turned and went into his house, and he didn’t even take this to heart. All the Egyptians dug around the river for water to drink; for they couldn’t drink the river water. Seven days were fulfilled, after Yahweh had struck the river.
Exodus 7:14-25 (World English Bible)
The sign of the staff becoming a serpent is the first public confrontation between Yahweh and the power of Egypt. The fact that Aaron's staff swallows the magicians' staffs is rich with symbolic meaning. In Egyptian iconography, the serpent represented royal authority and divine power — the uraeus on Pharaoh's crown symbolized his claim to deity. Aaron's staff swallowing the others demonstrates that Yahweh's authority supersedes and consumes all competing claims.
The plague of blood striking the Nile was a direct assault on Egypt's most vital resource and its most important deity. The Nile was the source of Egypt's life, fertility, and transportation. The Egyptians worshiped the Nile god Hapi and believed the river's annual flooding was a divine gift. Turning the Nile to blood demonstrated that Yahweh, not Hapi, controlled Egypt's water supply and could turn their source of life into a source of death.
The magicians' ability to replicate the plague of blood — making bad water worse — actually deepened the suffering rather than relieving it. This ironic detail shows the poverty of counterfeit power: it can imitate but never heal. The magicians could only add to the judgment, not remove it. This pattern continues through the early plagues, where the magicians' imitations only multiply the calamity.
Gospel connection
The contest between Yahweh and the magicians of Egypt prefigures the greater contest between Christ and the powers of darkness. Just as Aaron's staff swallowed the magicians' staffs, Christ's resurrection swallows the power of death and evil. The water turned to blood — a sign of judgment — points forward to the blood of Christ, which becomes the means of salvation rather than judgment for those who trust in Him.
Application
This chapter demonstrates that God's power is greater than any opposing force. Egypt's magicians could mimic but never overcome. When we face opposition that seems spiritually powerful, we can trust that God's power is ultimately superior. The hardening of Pharaoh's heart also serves as a warning: persistent resistance to God leads to a hardened heart that cannot repent.

Frequently asked questions
Why did the magicians replicate the plagues?
The magicians' ability to replicate the early signs shows that Egypt had genuine but limited supernatural power. Their ability to turn water to blood made the plague worse, not better, demonstrating that their power could not undo Yahweh's acts.
What does it mean that Aaron's staff swallowed their staffs?
The swallowing of the magicians' serpents is a symbolic victory. It demonstrates that Yahweh's power is greater than the power of Egypt's gods and magicians. The sign prefigures the total defeat of Egypt.
Why did God harden Pharaoh's heart?
The text presents both God hardening Pharaoh's heart and Pharaoh hardening his own. God's hardening is judicial — giving Pharaoh over to the stubbornness he already chose. It also serves to display God's power more fully through multiple plagues.
