¹⁷ This is what the Lord says: Here is how you will know that I am the Lord. Watch. I am about to strike the water in the Nile with the staff in my hand, and it will turn to blood.

¹⁹ “This is the finger of God,”^(A) the magicians said to Pharaoh. But Pharaoh’s heart was hard, and he would not listen to them, as the Lord had said.

²² But on that day I will give special treatment to the land of Goshen, where my people are living;^(A) no flies will be there. This way you will know that I, the Lord, am in the land.

⁴ I will harden Pharaoh’s heart so that he will pursue them. Then I will receive glory by means of Pharaoh and all his army, and the Egyptians will know that I am the Lord.” So the Israelites did this.^(A)

¹⁸ The Egyptians will know that I am the Lord when I receive glory through Pharaoh, his chariots, and his horsemen.”
