Pillar of cloud and fire
the Holy Bible

--Exodus--

And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: (13:21)

He took not away the pillar of the cloud by day, nor the pillar of fire by night, [from] before the people. (13:22)

And the angel of God, which went before the camp of Israel, removed and went behind them; and the pillar of the cloud went from before their face, and stood behind them: (14:19)

And it came between the camp of the Egyptians and the camp of Israel; and it was a cloud and darkness [to them], but it gave light by night [to these]: so that the one came not near the other all the night. (14:20)
