Exodus 7:17-20 ▼

17 Thus says Yahweh, “By this you shall know that I am Yahweh: behold, I am about to strike the water that is in the Nile with the staff that is in my hand, and it will be turned to blood.

18 And the fish that are in the Nile will die, and the Nile will become foul, and the Egyptians will be weary of drinking water from the Nile.”’”

19 Then Yahweh 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, and over their pools and over all their reservoirs of water, that they may become blood; and there will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’”

20 So Moses and Aaron did thus, as Yahweh had commanded. And he raised up the staff and struck the water that was in the Nile, in the sight of Pharaoh and in the sight of his servants, and all the water that was in the Nile was turned to blood.
