Exodus 7:17-19

Douay-Rheims 1899 American Edition

¹⁷ Thus therefore saith the Lord: In this thou shalt know that I am the Lord: behold I will strike with the rods that is in my hand, the water of the river, and it shall be turned into blood.

¹⁸ And the fishes that are in the river shall die, and the waters shall be corrupted, and the Egyptians shall be afflicted when they drink the water of the river.

¹⁹ The Lord also said to Moses: Say to Aaron, Take thy rod, and stretch forth thy hand upon the waters of Egypt, and upon their rivers, and streams and pools, and all the ponds of waters, that they may be turned into blood: and let blood be in all the land of Egypt, both in vessels of wood and of stone.
