Exodus 7:19-21

Living Bible

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.”

²⁰ So Moses and Aaron did as the Lord commanded them. As Pharaoh and all of his officials watched, Aaron hit the surface of the Nile with the rod, and the river turned to blood. ²¹ The fish died and the water became so foul that the Egyptians couldn’t drink it; and there was blood throughout the land of Egypt.
