Exodus 14:18-21

18And the Egyptians shall know that I am Jehovah, when I have gotten me honor upon Pharaoh, upon his chariots, and upon his horsemen. 19And the angel of God, who went before the camp of Israel, removed and went behind them; and the pillar of cloud removed from before them, and stood behind them: 20and it came between the camp of Egypt and the camp of Israel; and there was the cloud and the darkness, yet gave it light by night: and the one came not near the other all the night.

21And Moses stretched out his hand over the sea; and Jehovah caused the sea to go back by a strong east wind all the night, and made the sea dry land, and the waters were divided.
