14. Then the Lord said to Moses, “Pharaoh’s heart is hard: he refuses to let the people go.
15. Go to Pharaoh in the morning. When you see him walking out to the water, stand ready to meet him by the bank of the Nile. Take in your hand the staff that turned into a snake.
16. Tell him: Yahweh, the God of the Hebrews, has sent me to tell you: Let My people go, so that they may worship Me in the wilderness, but so far you have not listened.
17. This is what Yahweh says: Here is how you will know that I am Yahweh. Watch. I will strike the water in the Nile with the staff in my hand, and it will turn to blood.
