Exodus 14:19-22

19Then the angel of God, who was going in front of the Israelite forces, moved and went behind them. The pillar of cloud moved from in front of them and stood behind them.

20It came between the Egyptian and Israelite forces. There was cloud and darkness, it lit up the night, and neither group came near the other all night long.

21Then Moses stretched out his hand over the sea. The Lord drove the sea back with a powerful east wind all that night and turned the sea into dry land. So the waters were divided,

22and the Israelites went through the sea on dry ground, with the waters like a wall to them on their right and their left.
