Exodus 14:24-27

24And it came to pass, that in the morning watch Yhwh looked unto the army of the Egyptians through the pillar of fire and of the cloud, and troubled the army of the Egyptians, 25And took off their chariot wheels, that they drave them heavily: so that the Egyptians said, Let us flee from the face of Israel; for Yhwh fighteth for them against the Egyptians.1

26And Yhwh said unto Moses, Stretch out thine hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen. 27And Moses stretched forth his hand over the sea, and the sea returned to his strength when the morning appeared; and the Egyptians fled against it; and Yhwh overthrew the Egyptians in the midst of the sea.2
