Exod 14:21-25

21Then Moses stretched out his hand over the sea. The Lord drove the sea back by a strong east wind all night, and turned the sea into dry land; and the waters were divided.22The Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left.23The Egyptians pursued, and went into the sea after them, all of Pharaoh's horses, chariots, and chariot drivers.24At the morning watch the Lord in the pillar of fire and cloud looked down upon the Egyptian army, and threw the Egyptian army into panic.25He clogged their chariot wheels so that they turned with difficulty. The Egyptians said, “Let us flee from the Israelites, for the Lord is fighting for them against Egypt.”
