Exodus 33:8-12

And it came to pass, when Moses went out unto the Tent, that all the people rose up, and stood, every man at his tent door, and looked after Moses, until he was gone into the Tent. 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. And Moses said unto Jehovah, See, thou sayest unto me, Bring up this people: and thou hast not let me know whom thou wilt send with me. Yet thou hast said, I know thee by name, and thou hast also found favor in my sight.
