'Pillar of Fire' in the Bible

The [presence of the] Lord was going before them by day in a pillar (column) of cloud to lead them along the way, and in a pillar of fire by night to give them light, so that they could travel by day and by night.

He did not withdraw the pillar of cloud by day, nor the pillar of fire by night, from going before the people.

So it happened at the early morning watch [before dawn], that the Lord looked down on the army of the Egyptians through the pillar of fire and cloud and put them in a state of confusion.

and they will tell it to the inhabitants of this land. They have heard that You, Lord, are among these people [of Israel], that You, Lord, are seen face to face, while Your cloud stands over them; and that You go before them in a pillar of cloud by day and in a pillar of fire by night.

“And with a pillar of cloud You led them by day,And with a pillar of fire by nightTo light the way for themIn which they were to go.

You, in Your great mercy and compassion,Did not abandon them in the wilderness;The pillar of the cloud did not leave them by day,To lead them in the way,Nor the pillar of fire by night, to light for them the way they should go.
