Numbers 20:24-26

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.
