Exodus 14:19-25

The angel of God, who had been going in front of the camp of Israel, moved and went behind them. The pillar of the cloud moved from in front and stood behind them. So it came between the camp of Egypt and the camp of Israel. It was a cloud along with darkness [even by day to the Egyptians], but it gave light by night [to the Israelites]; so one [army] did not come near the other all night. Then Moses stretched out his hand over the sea; and the LORD swept the sea back by a strong east wind all that night and turned the seabed into dry land, and the waters were divided. The Israelites went into the middle of the sea on dry land, and the waters formed a wall to them on their right hand and on their left. 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.”
