Exodus 33:9-15 (NKJV)
And it came to pass, when Moses entered the tabernacle, that the pillar of cloud descended and stood at the door of the tabernacle, and the Lord talked with Moses. 10 All the people saw the pillar of cloud standing at the tabernacle door, and all the people rose and worshiped, each man in his tent door. 11 So 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. 12 Then 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.’ 13 Now therefore, I pray, if I have found grace in Your sight, show me now Your way, that I may know You and that I may find grace in Your sight. And consider that this nation is Your people.” 14 And He said, “My Presence will go with you, and I will give you rest.” 15 Then he said to Him, “If Your Presence does not go with us, do not bring us up from here.
