Exodus 7:19-21

DouayRheims(i) 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. 20 And Moses and Aaron did as the Lord had commanded: and lifting up the rod, he struck the water of the river before Pharao and his servants: and it was turned into blood. 21 And the fishes that were in the river died; and the river corrupted, and the Egyptians could not drink the water of the river, and there was blood in all the land of Egypt.
