Exodus 7:17-19

Living Bible

¹⁷ and now the Lord says this: “You are going to find out that I am God. For I have instructed Moses to hit the water of the Nile with his rod, and the river will turn to blood! ¹⁸ The fish will die and the river will stink, so that the Egyptians will be unwilling to drink it.”’”

¹⁹ Then the Lord instructed Moses: “Tell Aaron to point his rod toward the waters of Egypt: all its rivers, canals, marshes, and reservoirs, and even the water stored in bowls and pots in the homes will turn to blood.”
