Exodus 33:11-12

11So the Lord spoke to Moses face to face, as a man speaks to his friend. And he would return to the camp, but his servant Joshua the son of Nun, a young man, did not depart from the tabernacle.

12Then Moses said to the Lord, “See, You say to me, ‘Bring up this people.’ But You have not let me know whom You will send with me. Yet You have said, ‘I know you by name, and you have also found grace in My sight.’
