Numbers 20:24-26

²⁴Aaron shall be gathered unto his people: for he shall not enter into the land which I have given unto the children of Israel, because ye rebelled against my word at the water of Meribah.

²⁵Take Aaron and Eleazar his son, and bring them up unto mount Hor:

²⁶and strip Aaron of his garments, and put them upon Eleazar his son: and Aaron shall be gathered unto his people, and shall die there.
