Exodus 14:23-25

Then the Egyptians pursued them into the middle of the sea, even all Pharaoh’s horses, his war-chariots and his charioteers. So 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. He 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.”
