And Moses and Aaron did so, as the Lord commanded,.... Moses delivered the rod to Aaron, who took it and went to the water side:and he lift up the rod, and smote the waters that were in the river; or "in that river" , the river Nile, on the brink of which Pharaoh then stood:in the sight of Pharaoh, and in the sight of his servants; his nobles and courtiers who tended him in his walk to the water; for this was done before he returned to his palace:and all the waters that were in the river were turned into blood; not only the face of the waters looked like blood, but they were really turned into it; and not only the surface of the water, but all the water that was in the river, wherever it flowed, and as far as it flowed in the land of Egypt.
