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.
