Exodus 33
9 Ref And whenever Moses went into the Tent, the pillar of cloud came down, and took its place by the door of the Tent, as long as the Lord was talking with Moses.
10 Ref And all the people saw the cloud at the door of the Tent, and they went down on their faces, everyone at the door of his tent.
11 Ref And the Lord had talk with Moses face to face, as a man may have talk with his friend. And when Moses came back to the tents, his servant, the young man Joshua, the son of Nun, did not come away from the Tent.
