Exodus 7:22-24

Authorized (King James) Version

²² 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. ²³ And Pharaoh turned and went into his house, neither did he set his heart to this also. ²⁴ And all the Egyptians digged round about the river for water to drink; for they could not drink of the water of the river.
