Exodus 7:9-20
He said,“ Pharaoh will say to you,‘ Do a miracle.’ When he does, speak to Aaron. Tell him,‘ Take your walking stick and throw it down in front of Pharaoh.’ It will turn into a snake.”So Moses and Aaron went to Pharaoh. They did exactly as the Lord had commanded them. Aaron threw the stick down in front of Pharaoh and his officials. It turned into a snake.Then Pharaoh sent for wise men and people who do evil magic. By doing their magic tricks, the Egyptian magicians did the same things Aaron had done.Each one threw down his walking stick. Each stick turned into a snake. But Aaron’s walking stick swallowed theirs up.In spite of that, Pharaoh became stubborn. He wouldn’t listen to them, just as the Lord had said.Then the Lord said to Moses,“ Pharaoh is very stubborn. He refuses to let the people go.In the morning Pharaoh will go down to the Nile River. Go and meet him on the bank of the river. Take in your hand the walking stick that turned into a snake.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.”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 walking stick that is in my hand. The river will turn into blood.The fish in the river will die. The river will stink. The Egyptians will not be able to drink its water.” ’ ”The Lord said to Moses,“ Tell Aaron,‘ Get your walking stick. Reach your hand out over the waters of Egypt. The streams, canals, ponds and all the lakes will turn into blood. There will be blood everywhere in Egypt. It will even be in the wooden buckets and stone jars.’ ”Moses and Aaron did exactly as the Lord had commanded them. Aaron held out his staff in front of Pharaoh and his officials. He struck the water of the Nile River. And all the water turned into blood.
