Exodus 7
Exodus 7 opens the contest between the God of Israel and the gods of Egypt, and the opening move is a declaration of sovereignty: I have made you like God to Pharaoh. Moses is eighty, Aaron eighty-three. When Aaron's staff becomes a serpent and the Egyptian magicians replicate the sign, Aaron's serpent swallows theirs — a small but decisive preview of what is coming. Then the first plague begins: the Nile turns to blood. Every water source in Egypt — the river the Egyptians called a god, the source of their agricultural life — becomes blood. Fish die. The water is undrinkable. Yet Pharaoh's magicians replicate this too, Pharaoh's heart remains hard, and he walks away. The hardening of Pharaoh's heart, which will recur throughout the plague narrative, is both a judicial act — God confirming a direction Pharaoh has already chosen — and a theological statement about how resistance to God eventually becomes its own punishment. Romans 9:17 quotes God's purpose in raising up Pharaoh: that His name might be proclaimed in all the earth.
Exodus 7:1
The Lord said to Moses: see, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. The language is extraordinary — Moses is designated as like God before Pharaoh, and Aaron as his prophet, his mouthpiece. The structure mirrors the divine arrangement: as God speaks and prophets deliver His word, so Moses receives and Aaron declares. The relationship being described here is not one of equals but of source and voice. John 1:1 describes the Word in relation to God before creation: the same logic of delegated authority, the word going out from the source. Moses will be to Pharaoh what God is to Moses — the originating authority whose word must be reckoned with. This elevation does not make Moses divine; it makes him the representative of the divine in the most consequential negotiation of the ancient world.
Exodus 7:2
You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. The same charge given in 6:29 — say everything I tell you — is here distributed across the partnership: Moses receives, Aaron delivers. The chain of transmission is clean: God to Moses to Aaron to Pharaoh. Nothing is to be filtered, softened, or embellished. 2 Timothy 4:2 tells Timothy to preach the word in season and out of season — the same charge of complete and faithful transmission regardless of reception. Moses' history of objection has not changed the content of what he is being asked to carry. The message is what it always was: let my people go. The partnership is now fully operational, and the plagues are about to begin.
Exodus 7:3
But I will harden Pharaoh's heart, and though I multiply my signs and wonders in Egypt, he will not listen to you. God states the outcome in advance: Pharaoh will not listen, and God will multiply the signs. The hardening and the multiplication are causally connected — Pharaoh's resistance is the stage on which the signs will be performed, and the signs accumulate in response to the resistance. Romans 9:17 explains the purpose: so that my name might be proclaimed in all the earth. The plagues are not failed negotiations; they are proclamations. Each one names a different attribute of God's power, dismantles a different Egyptian claim, and contributes to the comprehensive demonstration that the Lord is God. The announcement that Pharaoh will not listen is not a reason for despair; it is the disclosure of the curriculum that is about to be taught to Egypt, Israel, and all who hear the story afterward.
