Numbers 20:24-26

²⁴Aaron shall be gathered unto his peoples; for he shall not enter into the land that I have given unto the children of Israel, because ye rebelled against my commandment at the waters 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 to his peoples, and shall die there.
