Numbers 20:22-28

²²And they removed from Kadesh; and the children of Israel, the whole assembly, came to mount Hor.

²³And Jehovah spoke to Moses and to Aaron in mount Hor, on the border of the land of Edom, saying,

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.

²⁷And Moses did as Jehovah had commanded, and they went up mount Hor before the eyes of the whole assembly.

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