Thus, saith Yahweh, Hereby, shalt thou know that, I, am Yahweh, - Lo! I, am smiting with the staff that is in my hand upon the waters that are in the river and they shall be turned to blood; and, the fish that is in the river shall die and the river shall be loathsome, - and the Egyptians, shall disdain, to drink water out of the river. And Yahweh said unto Moses, - Say unto Aaron - Take thy staff, and stretch forth thy hand over the waters of Egypt, over their streams over their rivers, and over their pools and over all their collections of water - that they may become blood, - so shall there be blood in all the land of Egypt, both in vessels of wood and in vessels of stone. read more.
And Moses and Aaron, did so, as Yahweh commanded, and he lifted high the staff, and smote the waters which were in the river, before the eyes of Pharaoh, and before the eyes of his servants, - and all the waters which were in the river were turned to blood; and the fish that was in the river, died and the river became loathsome, so that the Egyptians could not drink water out of the river, - thus came it to pass that blood was in all the land of Egypt. And the sacred scribes of Egypt did in like manner with their secret arts, - so the heart of Pharaoh waxed bold and he hearkened not unto them, as spake Yahweh. Then Pharaoh, turned away, and entered into his house - neither applied he his heart, even to this. And all the Egyptians digged round about the river for water to drink, - for they could not drink of the water of the river. And seven days were fulfilled, - after Yahweh had smitten the river.
