Exodus 14:22-26

So the sons of Israel went through the midst of the sea on the dry land, and the waters were like a wall to them on their right and on their left.

Then the Egyptians took up the pursuit, and all Pharaoh’s horses, his chariots, and his horsemen went in after them into the midst of the sea.

But at the morning watch, the Lord looked down on the army of the Egyptians through the pillar of fire and cloud, and brought the army of the Egyptians into confusion.

He caused their chariot wheels to swerve, and He made them drive with difficulty; so the Egyptians each said, “Let me flee from Israel, for the Lord is fighting for them against the Egyptians.”

Then the Lord said to Moses, “Reach out with your hand over the sea so that the waters may come back over the Egyptians, over their chariots and their horsemen.”
