Numbers 20:27 WEB

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

²⁶  and strip Aaron of his garments, and put them on Eleazar his son: and Aaron shall be gathered [to his people], and shall die there.

²⁷  Moses did as Yahweh commanded: and they went up into Mount Hor in the sight of all the congregation.

²⁸  Moses stripped Aaron of his garments, and put them on Eleazar his son; and Aaron died there on the top of the mountain: and Moses and Eleazar came down from the mountain.

²⁹  When all the congregation saw that Aaron was dead, they wept for Aaron thirty days, even all the house of Israel.
