Exodus 7:19-20 And the Lord said unto Moses, Say unto Aaron, Take thy staff, and stretch out thy hand over the waters of Egypt, over their streams, over their rivers, and over their ponds, and over all their pools of water, that they become blood; and there shall be blood throughout all the land of Egypt, also in vessels of wood, and in vessels of stone.

Leeser⁽ⁱ⁾ ¹⁹ And the Lord said unto Moses, Say unto Aaron, Take thy staff, and stretch out thy hand over the waters of Egypt, over their streams, over their rivers, and over their ponds, and over all their pools of water, that they become blood; and there shall be blood throughout all the land of Egypt, also in vessels of wood, and in vessels of stone. ²⁰ And Moses and Aaron did so, as the Lord had commanded; and he lifted up his hand with the staff, and smote the waters that were in the river, before the eyes of Pharaoh, and before the eyes of his servants; and all the waters that were in the river were turned to blood.
