The Book of Exodus

Chapter 7: The Rod and the River

The great contest begins. God sends Moses back to Pharaoh, making him "a god to Pharaoh" with Aaron as his prophet, and warns that Pharaoh's heart will be hardened so that God may multiply His signs and Egypt may know that He is the LORD. Aaron casts down his rod and it becomes a serpent; the magicians of Egypt copy the sign, but Aaron's rod swallows theirs. Then comes the first plague: at God's word Aaron stretches the rod over the waters, and the Nile, the lifeblood and god of Egypt, turns to blood. The fish die, the river stinks, and Egypt digs for water. Yet Pharaoh hardens his heart still. Exodus 7 is a chapter about the God whose power swallows every counterfeit, who begins His judgment on Egypt's false gods, and who is not stopped by the hardest heart.

Setting the Stage

The Charge

A God to Pharaoh

God makes Moses His representative before Pharaoh, with Aaron as prophet, so that Egypt will come to know that He is the LORD.

The Sign

The Rod That Swallowed the Rods

Aaron's rod becomes a serpent; the magicians copy the wonder, but Aaron's rod swallows theirs, God's power over the counterfeit.

The Plague

The River Turned to Blood

At God's word the Nile, the lifeline and god of Egypt, becomes blood; the fish die and the river stinks.

The Heart

Pharaoh Hardened

The magicians imitate the plague, and Pharaoh turns away unmoved, his heart hardened as the LORD had said.

The Charge

I Have Made Thee a God to Pharaoh (Exodus 7:1-7)

God sends Moses back as His representative, foretelling that Pharaoh's resistance will only serve to display God's power and make His name known.

Exodus 7:1-9

Moses and Aaron Sent Again

"And the LORD said unto Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet. Thou shalt speak all that I command thee: and Aaron thy brother shall speak unto Pharaoh, that he send the children of Israel out of his land. And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt. But Pharaoh shall not hearken unto you, that I may lay my hand upon Egypt, and bring forth mine armies, and my people the children of Israel, out of the land of Egypt by great judgments. And the Egyptians shall know that I am the LORD, when I stretch forth mine hand upon Egypt, and bring out the children of Israel from among them. And Moses and Aaron did as the LORD commanded them, so did they. And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh. And the LORD spake unto Moses and unto Aaron, saying, When Pharaoh shall speak unto you, saying, Shew a miracle for you: then thou shalt say unto Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent."

Hebrew Study

God's commission uses startling language: "I have made thee a god to Pharaoh" — nathatti elohim le-Pharaoh — Moses stands as God's representative, and Aaron is his prophet (navi, the mouthpiece who speaks another's words). Here too the chapter's key verb enters: "I will harden Pharaoh's heart" (qashah, to make stiff and unyielding). And the goal is set once for all: "the Egyptians shall know that I am the LORD" (yada YHWH) — the plagues are not mere punishment but revelation.

Explanation

God answers Moses' fears by defining his role: "I have made thee a god to Pharaoh." This does not mean Moses became divine; it means he would stand before Pharaoh as God's representative, speaking with God's authority, while Aaron would be his "prophet," his spokesman to relay the words. God then lays out the whole plan in advance: "I will harden Pharaoh's heart, and multiply my signs and my wonders." Pharaoh will refuse, and his refusal will only give God occasion to display His power in "great judgments," so that "the Egyptians shall know that I am the LORD." Moses and Aaron obey, and we are told Moses was eighty years old and Aaron eighty-three when they came before Pharaoh. God's great deliverance would be carried out by two old men, long past the age the world counts useful, because the power was never in them but in the LORD who sent them.

Gospel Focus

God announced beforehand that Pharaoh's resistance would not thwart His plan but serve it: "that I may lay my hand upon Egypt ... and the Egyptians shall know that I am the LORD." Even Pharaoh's hard heart was folded into God's purpose. Paul draws exactly this lesson: "the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth" (Romans 9:17). God is so sovereign that He can take the defiance of His enemies and make it the very stage on which His glory is displayed. This is a comfort when we face immovable opposition: the Pharaohs who resist God's people are not outside His control, but instruments He will use to make His name known. And notice the encouragement in the ages of Moses and Aaron, eighty and eighty-three. God's greatest work through them came when they were old. No one is past usefulness in the hands of God; He measures His servants not by their strength or their youth but by their surrender.

The Sign

Aaron's Rod Swallowed Their Rods (Exodus 7:8-13)

Aaron's rod becomes a serpent, and though the magicians copy the wonder, Aaron's rod swallows theirs, a sign of God's supremacy over every counterfeit power.

Exodus 7:10-16

The Magicians of Egypt Did in Like Manner

"And Moses and Aaron went in unto 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. Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods. And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said. And the LORD said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go. Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river's brink against he come; and the rod which was turned to a serpent shalt thou take in thine hand. And thou shalt say unto him, The LORD God of the Hebrews hath sent me unto thee, saying, Let my people go, that they may serve me in the wilderness: and, behold, hitherto thou wouldest not hear."

Hebrew Study

When the rod becomes a serpent before Pharaoh, the word is not nachash (as at the bush, 4:3) but tannin — a great reptile, the term for the Nile crocodile that Egypt revered and for the sea-dragon of Hebrew poetry. Pharaoh's magicians (chartummim) match the sign "with their enchantments," but Aaron's rod-serpent swallows up theirs. God's power does not merely rival Egypt's sacred symbols; it devours them whole.

Explanation

Aaron casts down the rod and it becomes a serpent, and Pharaoh answers by calling his wise men, sorcerers, and magicians, who "did in like manner with their enchantments," their rods also becoming serpents. There is real, dark power at work in their arts, not mere trickery, for God's word takes it seriously. But then comes the decisive moment: "Aaron's rod swallowed up their rods." Whatever power the magicians had, it was consumed by the power of God. They could imitate the sign, but they could not match it or stand against it. Pharaoh, however, is not moved, and his heart is hardened, "as the LORD had said." The first round ends with the counterfeit visibly defeated, yet the king refuses to bow.

Gospel Focus

The magicians of Egypt, whom the New Testament names as "Jannes and Jambres" who "withstood Moses" (2 Timothy 3:8), are a warning that the powers of darkness can imitate the works of God up to a point. This has always been so; the enemy is a counterfeiter, mimicking the true to deceive. But notice the limit and the outcome: Aaron's rod swallowed up their rods. The counterfeit could copy the sign but was consumed by the real power of God. This is our confidence against every dark and deceptive power: "greater is he that is in you, than he that is in the world" (1 John 4:4). The devil can imitate, oppose, and frighten, but he cannot win, for God's power swallows his. When we face the counterfeits and enchantments of our own day, we need not be afraid or impressed. The rod of God still swallows the rods of the sorcerers. The victory does not hang in doubt; the true power belongs to the LORD, and in the end every imitation is devoured by the genuine.

The Plague

The River Turned to Blood (Exodus 7:14-21)

The first plague strikes the Nile, the very lifeline and god of Egypt, turning its waters to blood so that Egypt may know the LORD.

Exodus 7:17-21

In This Thou Shalt Know That I Am the LORD

"Thus saith the LORD, In this thou shalt know that I am the LORD: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood. And the fish that is in the river shall die, and the river shall stink; and the Egyptians shall lothe to drink of the water of the river. And the LORD spake unto Moses, Say unto Aaron, Take thy rod, and stretch out thine hand upon the waters of Egypt, upon their streams, upon their rivers, and upon their ponds, and upon all their pools of water, that they may become blood; and that there may be blood throughout all the land of Egypt, both in vessels of wood, and in vessels of stone. And Moses and Aaron did so, as the LORD commanded; and he lifted up the rod, and smote 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. And the fish that was in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt."

Hebrew Study

The first plague strikes at Egypt's very lifeline: the river (ye'or, the Nile), worshipped as the god Hapi and the source of all the land's plenty, is smitten (nakah) and turned to blood. From the outset the plagues are aimed like arrows at Egypt's gods — the water that gave life now runs with death, and the deity of the Nile is shown powerless before the LORD.

Explanation

God tells Moses to meet Pharaoh at the river in the morning and announce the first plague: "In this thou shalt know that I am the LORD." The Nile was the heartbeat of Egypt, the source of all its water, food, and wealth, and the Egyptians worshiped it as a god. God strikes it first. Aaron stretches the rod over the waters, and "all the waters that were in the river were turned to blood." The fish die, the river stinks, the Egyptians cannot drink, and there is blood throughout the land, even in their vessels of wood and stone. The lifeline of Egypt becomes a river of death. This was not a random wonder but a direct blow: the god Egypt trusted for life could not even keep itself from becoming blood at the word of the true God.

Gospel Focus

The plagues were not only punishments; they were God's judgment on the false gods of Egypt. God said of the night of the Passover, "against all the gods of Egypt I will execute judgment: I am the LORD" (Exodus 12:12). Egypt worshiped the Nile, so God turned the Nile to blood, showing that the thing they trusted as a god was powerless before Him. This is how God often deals with idolatry: He strikes at the very things people put in His place, exposing them as unable to save. Whatever a person trusts instead of God, whether wealth, security, pleasure, or power, will one day be shown for what it is, unable to give life. The LORD alone is the living God; every rival is a broken cistern. And there is a solemn foreshadowing here too. The plague on the water answered Pharaoh's old cruelty, for he had commanded the Hebrew babies drowned in this very river; now the river ran with blood. God sees every injustice, and in His time He answers it. The true God will be known, either as Savior to those who trust Him or as Judge to those who defy Him.

The Heart

Pharaoh Set Not His Heart to This (Exodus 7:22-25)

The magicians imitate even this plague, and Pharaoh turns away unmoved, hardening his heart against the plain word of God.

Exodus 7:22-25

Neither Did He Set His Heart to This Also

"And the magicians of Egypt did so with their enchantments: and Pharaoh's heart was hardened, neither did he hearken unto them; as the LORD had said. And Pharaoh turned and went into his house, neither did he set his heart to this also. And all the Egyptians digged round about the river for water to drink; for they could not drink of the water of the river. And seven days were fulfilled, after that the LORD had smitten the river."

Hebrew Study

The magicians reproduce the wonder "with their enchantments," and the very success of the counterfeit is a snare: Pharaoh's heart is hardened, and he "turned and went into his house, neither did he set his heart to this also." For seven days the river festers. Imitation signs do not enlighten the proud; they deepen the delusion, giving the stubborn an excuse to ignore the hand of God.

Explanation

The magicians manage to imitate the plague, turning some water to blood themselves, which gives Pharaoh an excuse to dismiss the sign, though it did nothing to relieve his people's thirst. So "Pharaoh turned and went into his house, neither did he set his heart to this also." He simply walked away, unwilling to let the plain hand of God touch his heart. Meanwhile the ordinary Egyptians dug along the riverbank, desperate for water to drink, and seven days passed under the plague. Here we meet the hard theme that runs through the plague narrative: the hardening of Pharaoh's heart. Scripture says both that God hardened it and, elsewhere, that Pharaoh hardened his own, and the two are held together. Pharaoh was not an innocent man forced into sin; he was a proud, defiant king who set his own heart against God, and God, in righteous judgment, gave him over to the hardness he chose.

Gospel Focus

The hardening of Pharaoh's heart must be understood rightly. Scripture says "the LORD hardened Pharaoh's heart," and Paul writes, "whom he will he hardeneth" (Romans 9:18); yet the same account also says plainly that "Pharaoh ... hardened his heart" (Exodus 8:15). Both are true. Pharaoh first set himself against God in willful pride, and God, in just judgment, confirmed him in the hardness he had chosen. The same sun that melts wax hardens clay; the same word of God that softens a humble heart hardens a proud one. God did not force an unwilling man to sin; He gave a defiant man over to his own choice, and used even that for His glory. This is a sober warning. Every time we resist the plain dealing of God and "set not our heart to it," turning away and going into our house as Pharaoh did, our hearts grow a little harder. There is real danger in refusing God once we have seen His hand. The safe path is to soften under God's word at once, while it is still called today, lest resisting Him leave us, like Pharaoh, hardened past feeling. God's patience has a limit, and a heart that will not bend may at last become a heart that cannot.

Chapter 7 in Review

Exodus 7 opens the great contest with Pharaoh. God makes Moses His representative, "a god to Pharaoh," with Aaron as prophet, and foretells that Pharaoh's resistance will only display God's power until "the Egyptians shall know that I am the LORD." Aaron's rod becomes a serpent, and though the magicians copy the sign, Aaron's rod swallows theirs. Then the first plague falls: the Nile, Egypt's lifeline and god, is turned to blood, the fish die, and the land is left digging for water. Yet the magicians imitate even this, and Pharaoh turns away, hardening his heart against God.

For the Apostolic reader, this chapter displays the supremacy of God. He is so sovereign that even Pharaoh's defiance serves to make His name known, as Paul says He "raised up" Pharaoh to show His power. His rod swallows every counterfeit, for the dark powers can imitate but never overcome, and "greater is he that is in you, than he that is in the world." His plagues are judgment on false gods, striking the very Nile Egypt worshiped, a warning that everything we trust in God's place will fail us. And the hardening of Pharaoh's heart, held in the balance of God's judgment and Pharaoh's own pride, warns us never to resist the plain hand of God, lest a heart that will not bend become a heart that cannot. The true God will be known, as Savior or as Judge.

Key Takeaways
  • God is so sovereign that even His enemies' defiance serves to display His power and make His name known (7:3-5; Romans 9:17).
  • Dark powers can imitate God's works, but His power swallows every counterfeit (7:12; 2 Timothy 3:8; 1 John 4:4).
  • The plagues judge false gods; God struck the Nile that Egypt worshiped (7:20; Exodus 12:12).
  • The hardened heart is both God's judgment and Pharaoh's own choice; God gives the defiant over to their hardness (7:22; Romans 9:18; Exodus 8:15).
  • Resisting the plain hand of God hardens the heart; soften under His word while it is still today (7:23).

Questions for Reflection

  • God used even Pharaoh's defiance for His glory. How does that steady you when you face immovable opposition?
  • God struck the Nile that Egypt trusted. What might you be trusting in God's place that cannot truly give life?
  • Pharaoh "set not his heart" to God's dealing and grew harder. Is there a place you are resisting God that you need to soften today?
