Exodus 14:26-29

And Jehovah said unto Moses, Stretch out thy hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen. And Moses stretched forth his hand over the sea, and the sea returned to its strength when the morning appeared; and the Egyptians fled against it; and Jehovah overthrew the Egyptians in the midst of the sea. And the waters returned, and covered the chariots, and the horsemen, even all the host of Pharaoh that went in after them into the sea; there remained not so much as one of them. But the children of Israel walked upon dry land in the midst of the sea; and the waters were a wall unto them on their right hand, and on their left.
