Exodus 7:16-18

New International Version - UK

¹⁶ Then say to him, “The Lord, the God of the Hebrews, has sent me to say to you: let my people go, so that they may worship me in the wilderness. But until now you have not listened. ¹⁷ 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. ¹⁸ The fish in the Nile will die, and the river will stink; the Egyptians will not be able to drink its water.”’
