'Pillar of Fire' in the Bible

and Jehovah is going before them by day in a pillar of a cloud, to lead them in the way, and by night in a pillar of fire, to give light to them, to go by day and by night;

and it cometh to pass, in the morning watch, that Jehovah looketh unto the camp of the Egyptians through the pillar of fire and of the cloud, and troubleth the camp of the Egyptians,

and they have said it unto the inhabitant of this land, they have heard that Thou, Jehovah, art in the midst of this people, that eye to eye Thou art seen -- O Jehovah, and Thy cloud is standing over them, -- and in a pillar of cloud Thou art going before them by day, and in a pillar of fire by night.

And by a pillar of cloud Thou hast led them by day, and by a pillar of fire by night, to lighten to them the way in which they go.
