'Pillar of Cloud' in the Bible

And Jehovah came down in a pillar of cloud, and stood at the door of the Tent, and called Aaron and Miriam; and they both came forth.

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.
