Exodus 7 — Moses Before Pharaoh: Rod, Serpent, and Blood
Exodus 7 commissions Moses and Aaron before Pharaoh, Aaron's rod swallows the magicians' serpents, and the Nile and all Egyptian waters are struck and turned to blood for seven days, while Pharaoh's heart remains hardened.
Scripture
1And Jehovah said unto Moses, See, I have made thee as God to Pharaoh; and Aaron thy brother shall be thy prophet.
2Thou shalt speak all that I command thee; and Aaron thy brother shall speak unto Pharaoh, that he let the children of Israel go out of his land.
3And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt.
4But Pharaoh will not hearken unto you, and I will lay my hand upon Egypt, and bring forth my hosts, my people the children of Israel, out of the land of Egypt by great judgments.
5And the Egyptians shall know that I am Jehovah, when I stretch forth my hand upon Egypt, and bring out the children of Israel from among them.
6And Moses and Aaron did so; as Jehovah commanded them, so did they.
7And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh.
8And Jehovah spake unto Moses and unto Aaron, saying,
9When Pharaoh shall speak unto you, saying, Show a wonder for you; then thou shalt say unto Aaron, Take thy rod, and cast it down before Pharaoh, that it become a serpent.
10And Moses and Aaron went in unto Pharaoh, and they did so, as Jehovah had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
11Then Pharaoh also called for the wise men and the sorcerers: and they also, the magicians of Egypt, did in like manner with their enchantments.
12For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods.
13And Pharaoh's heart was hardened, and he hearkened not unto them; as Jehovah had spoken.
14And Jehovah said unto Moses, Pharaoh's heart is stubborn, he refuseth to let the people go.
15Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river's brink to meet him; and the rod which was turned to a serpent shalt thou take in thy hand.
16And thou shalt say unto him, Jehovah, the 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 hast not hearkened.
17Thus saith Jehovah, In this thou shalt know that I am Jehovah: behold, I will smite with the rod that is in my hand upon the waters which are in the river, and they shall be turned to blood.
18And the fish that are in the river shall die, and the river shall become foul; and the Egyptians shall loathe to drink water from the river.
19And Jehovah said unto Moses, Say unto Aaron, Take thy rod, and stretch out thy 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.
20And Moses and Aaron did so, as Jehovah 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.
21And the fish that were in the river died; and the river became foul, and the Egyptians could not drink water from the river; and the blood was throughout all the land of Egypt.
22And the magicians of Egypt did in like manner with their enchantments: and Pharaoh's heart was hardened, and he hearkened not unto them; as Jehovah had spoken.
23And Pharaoh turned and went into his house, neither did he lay even this to heart.
24And all the Egyptians digged round about the river for water to drink; for they could not drink of the water of the river.
25And seven days were fulfilled, after that Jehovah had smitten the river.
What this passage means
Paragraph 1: God's opening word to Moses, "I have made thee as God to Pharaoh," assigns Moses the place of an authorized spokesperson who issues divine commands to the king, while Aaron becomes his prophet, his mouthpiece to Pharaoh. The commission is paired with the demand to "let the children of Israel go out of his land," so the sign-act is never display for its own sake; every wonder is in service of the exodus demand.
Paragraph 2: God's declared intent to harden Pharaoh's heart (v. 3) and to multiply signs and wonders frames the confrontation as more than a negotiation. The magicians of Egypt respond by replicating the rod-into-serpent sign (7:11-12), but Aaron's rod swallows their rods, a graphic expression of the superiority of God's agent over Egypt's occult arts. The hardening formulation in v. 13 ("as Jehovah had spoken") then places the outcome within the announced word, not within Moses' persuasion.
Paragraph 3: The first plague, water turned to blood, is judged by its own test (v. 17, "In this thou shalt know that I am Jehovah"). The Nile, canals, streams, pools, ponds, and even water in wooden and stone vessels are covered (v. 19), making the strike total and domestic. Pharaoh's response ("neither did he lay even this to heart," v. 23) and the narrator's closing notice that "seven days were fulfilled" (v. 25) hold Pharaoh in view past the chapter's end, leaving the conflict unresolved.
Context
The chapter note states only that it is a backfilled chapter from Exodus outside P0/P1, so this page limits itself to the supplied verses and cross-references. The rod-to-serpent sign had already been given as a token earlier in the cycle (Exodus 4:9, 4:15, 4:16) for Israel, and here it is restaged before Pharaoh, with the commission language of Exodus 4:15-16 echoing in v. 1 ("as God to Pharaoh... thy prophet"). The hardening motif stated in v. 3 is consistent with the earlier divine warning of Exodus 4:21, and the goal of making Egypt "know that I am Jehovah" (v. 5) is later amplified in Exodus 14:18.
Egypt's response is two-layered: the magicians replicate the serpent (7:11-12) and later the blood (7:22), but cannot reverse the plague, and Pharaoh's hardening is repeatedly stated as a fulfillment of what God had spoken (vv. 13, 22). The Psalmist and Gospel writers later pick up the title "gods" language of v. 1 in Psalms 82:6 and John 10:35-36, applying it to those who receive and carry the word of God. Jeremiah 1:10 extends the same pattern of authorized declaration over nations in a later prophet, and Exodus 3:18 supplies the exact demand-formula ("let my people go, that they may serve me") reused in v. 16.
Key words in the original
- H0430 אֱלֹהִים (ʾĕlōhiym), "God," used in v. 1 in the unusual phrase "as God to Pharaoh" — Moses stands in God's place of authority to speak to the king. The same plural form is applied to those who receive God's word in Psalms 82:6 and John 10:35-36, where scripture defends the broader application as unbroken.
- H5030 נָבִיא (nāḇî), "prophet," gloss in v. 1: "prophet." Aaron is called Moses' prophet to Pharaoh — not a predictor but a mouthpiece, the one who carries the words put into his mouth (cf. Exodus 4:15-16).
- H7971 שָׁלַח (šālaḥ), gloss in v. 2: "let ~ go," "send away." The verb carries the demand-formula "let my people go" (also v. 16, cf. Exodus 3:18), turning the entire sign sequence into an acted-out request for release, not a display of power alone.
Related verses
- Exodus 4:15 The commissioning language of v. 1 ("as God to Pharaoh... thy prophet") is a direct echo of Exodus 4:15-16, where God tells Moses "I will be with thy mouth, and with his mouth." Chapter 7 stages what chapter 4 promised.
- Exodus 4:21 Exodus 7:3-4, "I will harden Pharaoh's heart, and multiply my signs and my wonders," restates the earlier warning of Exodus 4:21 that Pharaoh would not listen despite the wonders. Chapter 7 simply carries out what 4:21 announced.
- John 10:35 John 10:35 takes up v. 1's striking phrase "as God to Pharaoh" when it defends the scriptural use of "gods" for those "unto whom the word of God came," arguing the scripture cannot be broken. Moses' authority before Pharaoh is the Old Testament case the Gospel writer cites.
Common questions
Why is Moses called "as God to Pharaoh" in Exodus 7:1?
Because Moses stands in God's place as authorized spokesperson, issuing divine commands to the king, while Aaron serves as his prophet or mouthpiece. This mirrors the earlier commissioning in Exodus 4:15-16, where God says, "I will be with thy mouth, and with his mouth, and will teach you what ye shall do."
What is the significance of Aaron's rod swallowing the magicians' rods?
When the magicians of Egypt also cast down rods that became serpents (7:11-12), Aaron's rod swallowing theirs pictures the superiority of God's agent over Egypt's occult arts. The contrast sets the terms for the rest of the plague cycle: Egypt's experts can mimic signs, but cannot reverse them.
Why does the plague of blood continue for seven days (Exodus 7:25)?
The narrator's closing notice that "seven days were fulfilled" emphasizes that Pharaoh did not relent and God did not lift the blow. After that interval, the next plague begins in chapter 8, so the seven-day duration marks Pharaoh's unyielding stance and the unresolved tension that carries the confrontation forward.
