Exodus 7:11-22

11Then Pharaoh also summoned wise men and sorcerers, and the magicians of Egypt by their secret arts did the same thing.

12Each man threw down his staff, and the staffs became snakes. But Aaron’s staff swallowed up their staffs.

13Yet Pharaoh’s heart became hard, and he did not listen to them, just as the Lord had predicted.

14The Lord said to Moses, “Pharaoh’s heart is hard; he refuses to release the people.

15Go to Pharaoh in the morning when he goes out to the water. Position yourself to meet him by the edge of the Nile, and take in your hand the staff that was turned into a snake.

16Tell him, ‘The Lord, the God of the Hebrews, has sent me to you to say, “Release my people, that they may serve me in the desert!” But until now you have not listened.

17Thus says the Lord: “By this you will know that I am the Lord: I am going to strike the water of the Nile with the staff that is in my hand, and it will be turned into blood.

18Fish in the Nile will die, the Nile will stink, and the Egyptians will be unable to drink water from the Nile.”’”

19Then the Lord said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over Egypt’s waters – over their rivers, over their canals, over their ponds, and over all their reservoirs – so that it becomes blood.’ There will be blood everywhere in the land of Egypt, even in wooden and stone containers.”

20Moses and Aaron did so, just as the Lord had commanded. Moses raised the staff and struck the water that was in the Nile right before the eyes of Pharaoh and his servants, and all the water that was in the Nile was turned to blood.

21When the fish that were in the Nile died, the Nile began to stink, so that the Egyptians could not drink water from the Nile. There was blood everywhere in the land of Egypt!

22But the magicians of Egypt did the same by their secret arts, and so Pharaoh’s heart remained hard, and he refused to listen to Moses and Aaron – just as the Lord had predicted.
