Every country has something it depends on so completely that people barely think about it: the monsoon, the river, the power grid. When it fails, everything stops. For Egypt that was the Nile. It watered the fields, carried the boats, fed the fish and was honoured in Egyptian religion as a source of life. Exodus 7 opens the contest between Pharaoh and the LORD, and the first blow does not land on an army or a palace. It lands on the river, the thing Egypt could least imagine losing.
Where it sits in the story: After two chapters of setbacks, the confrontation proper begins. This is the start of the plagues, the long sequence in which God answers Pharaoh's question from chapter 5, 'Who is the LORD?' The text says the aim is that 'the Egyptians shall know that I am the LORD'. This is also where the theme of Pharaoh's hard heart becomes central, a thread that runs until the sea closes in chapter 14.
What this chapter is doing: To begin the plagues as signs of the LORD's authority over Egypt and its gods, and to show Pharaoh choosing, and being confirmed in, a hardened refusal.
- 7:1–7 — God makes Moses 'like God' to Pharaoh, with Aaron as his prophet. God says he will harden Pharaoh's heart and multiply signs, so that Egypt will know who he is. Moses is eighty and Aaron eighty-three when they obey.
- 7:8–13 — Aaron throws down his staff and it becomes a serpent. Pharaoh's magicians do the same by their secret arts, but Aaron's staff swallows theirs. A clear sign, and still Pharaoh's heart is hard.
- 7:14–25 — At the river in the morning Moses warns Pharaoh, then Aaron strikes the water. The Nile and Egypt's waters turn to blood, the fish die, the river stinks, and people dig beside it for water. The magicians copy the sign, Pharaoh walks back into his house unmoved, and seven days pass.
- God confirms a choice Pharaoh has already made: the early plagues stress Pharaoh's own stubbornness, and God's hardening gives him over to it (a common view in both Jewish and Christian reading).
- God's sovereignty is primary: God hardens Pharaoh to display his power and name (see Exodus 9:16, quoted in Romans 9:17), without denying Pharaoh's responsibility.
- Literary reading: the variation is the story's way of holding divine purpose and human choice together without resolving the tension.
Key verse: Exodus 7:5 · So what: Pharaoh sees a sign, watches his experts copy it and decides he does not need to change. The chapter is a study in how people can resist something plain because accepting it would cost too much. It asks readers of any belief a searching question: what would it actually take for me to change my mind, and am I honest about that?
