Exodus 14:27-29

27So Moses stretched out his hand over the sea, and the sea returned to its normal flow at sunrise; and the Egyptians retreated right into it [being met by the returning water]; so the Lord overthrew the Egyptians and tossed them into the midst of the sea.

28The waters returned and covered the chariots and the charioteers, and all the army of Pharaoh that had gone into the sea after them; not even one of them survived.

29But the Israelites walked on dry land in the middle of the sea, and the waters formed a wall to them on their right hand and on their left.
