Exodus 14:18-21 ESV
And the Egyptians shall know that I am the LORD, when I have gotten glory over Pharaoh, his chariots, and his horsemen.” Then the angel of God who was going before the host of Israel moved and went behind them, and the pillar of cloud moved from before them and stood behind them, coming between the host of Egypt and the host of Israel. And there was the cloud and the darkness. And it lit up the night without one coming near the other all night. Then Moses stretched out his hand over the sea, and the LORD drove the sea back by a strong east wind all night and made the sea dry land, and the waters were divided.
