Exodus 33:11-12

11Inside the Tent of Meeting, the Lord would speak to Moses face to face, as one speaks to a friend. Afterward Moses would return to the camp, but the young man who assisted him, Joshua son of Nun, would remain behind in the Tent of Meeting.

12One day Moses said to the Lord, “You have been telling me, ‘Take these people up to the Promised Land.’ But you haven’t told me whom you will send with me. You have told me, ‘I know you by name, and I look favorably on you.’
