Exodus 13:21

21And athe Lord went before them by day in a pillar of cloud to lead them along the way, and by night in a pillar of fire to give them light, that they might travel by day and by night.

Exodus 14:19-20

19 bThen 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, 20coming between the host of Egypt and the host of Israel. And there was the cloud and the darkness. And it lit up the night
Septuagint  and the night passed
without one coming near the other all night.
