Then the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. You are to say everything I command you, and your brother Aaron tells Pharaoh to let the Israelites go out of his country. But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in Egypt, he will not listen to you. Then I will lay my hand on Egypt, and with mighty acts of judgment, I will bring out my divisions, my people the Israelites. And the Egyptians will know that I am the Lord when I stretch out my hand against Egypt and bring the Israelites out of it.”

This is what the Lord says: By this, you will know that I am the Lord: With the staff that is in my hand, I will strike the water of the Nile, and it will be changed into blood. The fish in the Nile will die, and the river will stink; the Egyptians will not be able to drink its water.’”
The Lord said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt — over the streams and canals, over…
