Num 20:25-28

25Take Aaron and his son Eleazar, and bring them up Mount Hor;26strip Aaron of his vestments, and put them on his son Eleazar. But Aaron shall be gathered to his people, and shall die there.”27Moses did as the Lord had commanded; they went up Mount Hor in the sight of the whole congregation.28Moses stripped Aaron of his vestments, and put them on his son Eleazar; and Aaron died there on the top of the mountain. Moses and Eleazar came down from the mountain.
