Exodus 33:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ When Moses entered the tent, the pillar of cloud would descend and stand at the entrance of the tent, and the Lord would speak with Moses. ¹⁰ When all the people saw the pillar of cloud standing at the entrance of the tent, all the people would rise and bow down, all of them, at the entrance of their tents. ¹¹ Thus the Lord used to speak to Moses face to face, as one speaks to a friend. Then he would return to the camp; but his young assistant, Joshua son of Nun, would not leave the tent.
