Exodus 14:20-24

So it came between the camp of Egypt and the camp of Israel; and there was the cloud along with the darkness, yet it gave light at night. Therefore the one did not approach the other all night.

Then Moses reached out with his hand over the sea; and the Lord swept the sea back by a strong east wind all night, and turned the sea into dry land, and the waters were divided.

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.
