'Pillar of Fire' in the Bible

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: that they might go both by day and night.

And the pillar of the cloud never departed by day nor the pillar of fire by night out of the people's sight.

And it will be told to the inhabiters of this land also, for they have heard likewise, that thou the LORD art among this people, and that thou art seen face to face, and that thy cloud standeth over them and that thou goest before them by day time in a pillar of cloud, and in a pillar of fire by night.

and leddest them in the daytime in a cloudy pillar; and on the night season in a pillar of fire, to show them light in the way that they went.

yet thou forsookest them not in the wilderness, according to thy great mercy. And the cloudy pillar departed not from them in the daytime to lead them the way, neither the pillar of fire in the night season, to show them light in the way that they went.
