Exodus 14:24-27

24So it happened at the early morning watch [before dawn], that the Lord looked down on the army of the Egyptians through the pillar of fire and cloud and put them in a state of confusion.

25He made their chariot wheels hard to turn, and the chariots difficult to drive; so the Egyptians said, “Let us flee from Israel, for the Lord is fighting for them against the Egyptians.”

26Then the Lord said to Moses, “Stretch out your hand over the sea so that the waters may come back over the Egyptians, on their war-chariots and their charioteers.”

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.
