Exodus 33:8-11

8And it came to pass, when Moses went out to the tent, all the people rose up, and stood every man at the entrance of his tent, and they looked after Moses until he entered into the tent.

9And it came to pass when Moses entered into the tent, the pillar of cloud descended, and stood at the entrance of the tent, and [Jehovah] talked with Moses.

10And all the people saw the pillar of cloud standing at the entrance of the tent; and all the people rose and worshipped, every man at the entrance of his tent.

11And Jehovah spoke with Moses face to face, as a man speaks with his friend. And he returned to the camp; but his attendant, Joshua the son of Nun, a young man, departed not from within the tent.
