Exodus 7:17-21

Amplified Bible, Classic Edition

¹⁷ Thus says the Lord, In this you shall know, recognize, and understand that I am the Lord: behold, I will smite with the rod in my hand the waters in the [Nile] River, and they shall be turned to blood.

¹⁸ The fish in the river shall die, the river shall become foul smelling, and the Egyptians shall loathe to drink from it.

¹⁹ And the Lord said to Moses, Say to Aaron, Take your rod and stretch out your hand over the waters of Egypt, over their streams, rivers, pools, and ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, in containers both of wood and of stone.

²⁰ Moses and Aaron did as the Lord commanded; [Aaron] lifted up the rod and smote the waters in the river in the sight of Pharaoh and his servants, and all the waters in the river were turned to blood.

²¹ And the fish in the river died; and the river became foul smelling, and the Egyptians could not drink its water, and there was blood throughout all the land of Egypt.
