Numbers 20:25-28

25Take Aaron and his son 1Eleazar and bring them up to Mount Hor;

26and strip Aaron of his garments and put them on his son Eleazar. So Aaron will be 2gathered to his people, and will die there.”

27So Moses did just as the Lord had commanded, and they went up to Mount Hor in the sight of all the congregation.

28After Moses had stripped Aaron of his garments and 3put them on his son Eleazar, 4Aaron died there on the mountain top. Then Moses and Eleazar came down from the mountain.
