Ambrose of Milan, on Josh 1:1

“Now it came to pass after the death of Moses the servant of the Lord, that the Lord spoke to Josue the son of Nun, the minister of Moses, and said to him:”

“Joshua the son of Nun became so great, because his union with Moses was the means not only of instructing him in a knowledge of the law but also of sanctifying him to receive grace. When in his tabernacle the majesty of the Lord was seen to shine forth in its divine Presence, Joshua alone was in the tabernacle. When Moses spoke with God, Joshua too was covered by the sacred cloud. The priests and people stood below, and Joshua and Moses went up the mount to receive the law. All the people were within the camp; Joshua was without the camp in the tabernacle of witness. When the pillar of a cloud came down and God spoke with Moses, Joshua stood as a trusty servant beside him. He, a young man, did not go out of the tabernacle, though the old men who stood far off trembled at these divine wonders.”
