'Pillar of Fire' in the Bible

And Jehovah went before them by day in a pillar of cloud, to lead them the way, and by night in a pillar of fire, to give them light, that they might go by day and by night:

the pillar of cloud by day, and the pillar of fire by night, departed not from before the people.

And it came to pass in the morning watch, that Jehovah looked forth upon the host of the Egyptians through the pillar of fire and of cloud, and discomfited the host of the Egyptians.

and they will tell it to the inhabitants of this land. They have heard that thou Jehovah art in the midst of this people; for thou Jehovah art seen face to face, and thy cloud standeth over them, and thou goest before them, in a pillar of cloud by day, and in a pillar of fire by night.

Moreover in a pillar of cloud thou leddest them by day; and in a pillar of fire by night, to give them light in the way wherein they should go.

yet thou in thy manifold mercies forsookest them not in the wilderness: the pillar of cloud departed not from over them by day, to lead them in the way; neither the pillar of fire by night, to show them light, and the way wherein they should go.
