15 Go to Pharaoh in the morning as he is coming out to the water, and stand ready to meet him by the bank of the Nile. Take the staff that was transformed into a serpent in your hand.
16 You are to say to him: Adonai, God of the Hebrews, has sent me to you, saying, ‘Let My people go, so they may serve Me in the wilderness,’ and behold, you have not listened.
17 This is what Adonai says: ‘By this you will know that I am Adonai. Behold, I will strike the waters that are in the river with the staff that is in my hand, and they will be turned to blood.
18 The fish that are in the river will die, the river will become foul, and the Egyptians will hate to drink water from the Nile.”’
19 Adonai said to Moses, “Say to Aaron: Take your staff and stretch out your hand over the waters of Egypt, over their rivers, over their streams, over their pools and over all their ponds, so that they become blood. There will be blood throughout all the land of Egypt, even in wooden and stone containers.”
20 So Moses and Aaron did as Adonai commanded. He lifted up the staff and struck the waters that were in the river in the sight of Pharaoh and his servants, and all the waters of the Nile turned to blood.
21 When the fish that were in the river died, the river became so foul that the Egyptians could not drink water from the river. The blood was throughout all the land of Egypt.
