Exodus 7:19-21 And the Lord said to Moses, Say to your brother Aaron, Take your rod in your hand, and stretch forth your hand over the waters of Egypt, and over their rivers, and over their canals, and over their ponds, and over all their standing water, and it shall become blood: and there was blood in all the land of Egypt, both in vessels of wood and of stone.

LXX2012⁽ⁱ⁾ ¹⁹ And the Lord said to Moses, Say to your brother Aaron, Take your rod in your hand, and stretch forth your hand over the waters of Egypt, and over their rivers, and over their canals, and over their ponds, and over all their standing water, and it shall become blood: and there was blood in all the land of Egypt, both in vessels of wood and of stone. ²⁰ and Moses and Aaron did so, as the Lord commanded them; and [Aaron] having lifted up [his hand] with his rod, struck the water in the river before Pharao, and before his servants, and changed all the water in the river into blood. ²¹ And the fish in the river died, and the river stank thereupon; and the Egyptians could not drink water from the river, and the blood was in all the land of Egypt.
