Exodus 7:17-19

New Century Version

¹⁷ This is what the Lord says: ‘This is how you will know that I am the Lord. I will strike the water of the Nile River with this stick in my hand, and the water will change into blood. ¹⁸ Then the fish in the Nile will die, and the river will begin to stink. The Egyptians will not be able to drink the water from the Nile.’”

¹⁹ The Lord said to Moses, “Tell Aaron: ‘Take the walking stick in your hand and stretch your hand over the rivers, canals, ponds, and pools in Egypt.’ The water will become blood everywhere in Egypt, both in wooden buckets and in stone jars.”
