'Pillar' in the Bible

And Jehovah cometh down in the pillar of the cloud, and standeth at the opening of the tent, and calleth Aaron and Miriam, and they come out both of them.

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.
