Numbers 20:24-29

²⁴“Aaron shall be gathered to his people; for he shall not enter into the land which I have given to the children of Israel, because you rebelled against my word at the waters of Meribah.

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

²⁶and strip Aaron of his garments, and put them on Eleazar his son. Aaron shall be gathered, and shall die there.”

²⁷Moses did as Yahweh commanded. They went up onto Mount Hor in the sight of all the congregation.

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

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