Exodus 7:18-20

New Catholic Bible

¹⁸ The fish in the Nile will die, and the Nile will become putrid so that the Egyptians will not be able to drink from the Nile.” ’ ”

¹⁹ The Lord said to Moses, “Command Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt, over their rivers, their canals, their ponds, and over all their supplies of water. They will turn into blood and there will be blood in all of the land of Egypt, even in their wood and stone jars.’ ”

²⁰ Moses and Aaron did what the Lord had commanded. Aaron raised his staff and struck the waters of the Nile in the sight of Pharaoh and his servants. All the waters of the Nile changed into blood.
