Exodus 7:22-24

Holman Christian Standard Bible

²² But the magicians of Egypt did the same thing by their occult practices. So Pharaoh’s heart hardened, and he would not listen to them, as the Lord had said. ²³ Pharaoh turned around, went into his palace, and didn’t even take this to heart. ²⁴ All the Egyptians dug around the Nile for water to drink because they could not drink the water from the river.
