Numbers 20:22-26

22Now when they set out from 1Kadesh, the sons of Israel, the whole congregation, came to Mount Hor.

23Then the Lord spoke to Moses and Aaron at 2Mount Hor by the border of the land of Edom, saying,

24“Aaron will be 3gathered to his people; for he shall not enter the land which I have given to the sons of Israel, because 4you rebelled against My 5command at the waters of Meribah.

25Take Aaron and his son 6Eleazar and bring them up to Mount Hor;

26and strip Aaron of his garments and put them on his son Eleazar. So Aaron will be 7gathered to his people, and will die there.”
