‏ Exodus 7:19

19Then the Lord said to Moses, “Say to Aaron, ‘Take your staff and astretch out your hand over the waters of Egypt, over their rivers, over their ▼
▼ Or canals
streams, and over their pools, and over all their reservoirs of water, that they may become blood; and there will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’”
