Numbers 20:21-26

²¹So Edom would not let Israel go through his land; and Israel went in another direction.

²²And they went on from Kadesh, and came, with all their people, to Mount Hor.

²³And at Mount Hor, at the edge of the land of Edom, the Lord said to Moses and Aaron,

²⁴Aaron will be put to rest with his people; he will not go into the land which I have given to the children of Israel, because you went against my word at the waters of Meribah.

²⁵So take Aaron and Eleazar, his son, up into Mount Hor;

²⁶And take Aaron's robes off him and put them on Eleazar, his son: and death will come to Aaron there, and he will be put to rest with his people.
