Exodus 14:19-22

19Then the angel of God, who had been leading the people of Israel, moved to the rear of the camp. The pillar of cloud also moved from the front and stood behind them.

20The cloud settled between the Egyptian and Israelite camps. As darkness fell, the cloud turned to fire, lighting up the night. But the Egyptians and Israelites did not approach each other all night.

21Then Moses raised his hand over the sea, and the Lord opened up a path through the water with a strong east wind. The wind blew all that night, turning the seabed into dry land.

22So the people of Israel walked through the middle of the sea on dry ground, with walls of water on each side!
