1The Lord said to Moses, “I will be with you. You will be like a great king to Pharaoh. And Aaron will be your official speaker. 2Tell Aaron everything that I command you. Then he will tell the king the things I say. And Pharaoh will let the people of Israel leave this country. 3But I will make Pharaoh stubborn. ˻He will not obey the things you tell him.˼ Then I will do many miracles in Egypt to prove who I am. But he will still refuse to listen. 4So then I will punish Egypt very much. And I will lead my people out of that land. 5Then the people of Egypt will know that I am the Lord. I will be against them, and they will know that I am the Lord. Then I will lead my people out of their country.” 6Moses and Aaron obeyed these things the Lord told them. 7Moses was 80 years old at the time, and Aaron was 83. 8The Lord said to Moses and Aaron, 9“Pharaoh will ask you to prove your power. He will ask you to do a miracle. Tell Aaron to throw his walking stick on the ground. While Pharaoh is watching, the stick will become a snake.” 10So Moses and Aaron went to Pharaoh and obeyed the Lord. Aaron threw his walking stick down. While Pharaoh and his officers watched, the stick became a snake. 11So the king called for his wise men and magicians. These men used their tricks and they were able to do the same thing as Aaron. 12They threw their walking sticks on the ground, and their sticks became snakes. But then Aaron’s walking stick ate theirs. 13Pharaoh still refused to let the people go. This happened just like the Lord said it would. The king refused to listen to Moses and Aaron. 14Then the Lord said to Moses, “Pharaoh is being stubborn. Pharaoh refuses to let the people go. 15In the morning, Pharaoh will go out to the river. Go to him by the edge of the Nile River. Take the walking stick that became a snake. 16Tell him this: 'The Lord, the God of the Hebrew people, sent me to you. The Lord told me to tell you to let his people go worship him in the desert. Until now you have not listened to the Lord. 17So the Lord says that he will do something to show you that he is the Lord. I will hit the water of the Nile River with this walking stick in my hand, and the river will change into blood. 18The fish in the river will die, and the river will begin to stink. Then the Egyptians will not be able to drink the water from the river.’” 19The Lord said to Moses: “Tell Aaron to hold the walking stick in his hand over the rivers, canals, lakes and every place where they store water. When he does this, all the water will change into blood. All of the water, even the water stored in wood and stone jars, will change into blood.” 20So Moses and Aaron did what the Lord commanded. Aaron raised the walking stick and hit the water in the Nile River. He did this in front of Pharaoh and his officials. So all the water in the river changed into blood. 21The fish in the river died, and the river began to stink. So the Egyptians could not drink water from the river. The blood was everywhere in Egypt. 22The magicians used their tricks and did the same thing. So Pharaoh refused to listen to Moses and Aaron. This happened just like the Lord said. 23Pharaoh ignored what Moses and Aaron had done. Pharaoh just turned and went into his house. 24The Egyptians could not drink the water from the river. So they dug wells around the river for water to drink. 25Seven days passed after the Lord changed the Nile River.
