26Remove Aaron’s priestly garments and put them on his son Eleazar. Aaron will be gathered to his people and will die there.”
27So Moses did as the LORD had commanded, and they climbed Mount Hor in the sight of the whole congregation.
28After Moses had removed Aaron’s garments and put them on his son Eleazar, Aaron died there on top of the mountain. Then Moses and Eleazar came down from the mountain.
