'Pillar of Fire' in the Bible

You led them during the day by a pillar of cloud, and by a pillar of fire at night to provide light for them on the path they took.

You, in your great compassion, did not abandon them in the wilderness. The pillar of cloud did not leave them in daylight, in order to provide light for them on the path they took. Nor did the pillar of fire abandon them at night, in order to provide light for them and lead them on the path they took.
