Exodus 33:10-11

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.
