Exodus 14:19-22

19Then 1the angel of God, who had been going before the camp of Israel, moved and went behind them; and the pillar of cloud moved from before them and stood behind them. 20So it came between the camp of Egypt and the camp of Israel; and there was the cloud 2along with the darkness, yet it gave light at night. Therefore the one did not approach the other all night.

213Then Moses reached out with his hand over the sea; and the Lord 4swept the sea back by a strong east wind all night, and turned the sea into 5dry land, and 6the waters were divided. 22So 7the sons of Israel 8went through the midst of the sea on the dry land, and 9the waters were like a wall to them on their right and on their left.
