13 In spite of that, Pharaoh's heart became stubborn. He wouldn't listen to them, just as the Lord had said.
14 Then the Lord said to Moses, "Pharaoh's heart is very stubborn. He refuses to let the people go.
15 In the morning Pharaoh will go down to the water. Go and wait on the bank of the Nile River to meet him. Take in your hand the wooden staff that turned into a snake.
16 "Say to Pharaoh, 'The Lord, the God of the Hebrews, has sent me to you. He says, "Let my people go. Then they will be able to worship me in the desert. But up to now you have not listened."
17 " 'The Lord says, "Here is how you will know that I am the Lord. I will strike the water of the Nile River with the staff that is in my hand. The river will turn into blood.
18 The fish in the river will die. The river will stink. The Egyptians will not be able to drink its water." ' "
19 The Lord said to Moses, "Tell Aaron, 'Get your staff. Reach your hand out over the waters of Egypt. The streams, waterways, ponds and all of the lakes will turn into blood. There will be blood everywhere in Egypt. It will even be in the wooden buckets and stone jars.' "
