Exodus 33:9-11

And it came to pass, when Moses entered into the Tent, the pillar of cloud descended, and stood at the door of the Tent: and Jehovah spake with Moses. And all the people saw the pillar of cloud stand at the door of the Tent: and all the people rose up and worshipped, every man at his tent door. And Jehovah spake unto Moses face to face, as a man speaketh unto his friend. And he turned again into the camp: but his minister Joshua, the son of Nun, a young man, departed not out of the Tent.
