Numbers 20:21-26

²¹Thus Edom refused to give Israel passage through his border: wherefore Israel turned away from him.

²²And the children of Israel, even the whole congregation, journeyed from Kadesh, and came unto mount Hor.

²³And the LORD spake unto Moses and Aaron in mount Hor, by the coast of the land of Edom, saying,

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.
