Numbers 20:25 WEB

²³  Yahweh spoke to Moses and Aaron in Mount Hor, by the border of the land of Edom, saying,

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.

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.
