Exodus 14:18-20 New American Standard Bible (NASB)
18 Then the Egyptians will know that I am the Lord, when I am honored through Pharaoh, through his chariots and his horsemen.”
19 The 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. 20 So it came between the camp of Egypt and the camp of Israel; and there was the cloud [a]along with the darkness, yet it gave light at night. Thus the one did not come near the other all night.
