13. Yet Pharaoh’s heart was hardened. So he did not listen to them— just as Adonai had said.
14. Then Adonai said to Moses, “Pharaoh’s heart is stubborn; he refuses to let the people go.
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.”
