Exodus 14:27-29

27And Moses stretched out his hand over the sea, and the sea returned to its strength toward the morning; and the Egyptians fled against it; and Jehovah overturned the Egyptians into the midst of the sea.

28And the waters returned, and covered the chariots and the horsemen of all the host of Pharaoh that had come into the sea after them; there remained not even one of them.

29And the children of Israel walked on dry [ground] through the midst of the sea; and the waters were a wall to them on their right hand and on their left.
