Numbers 20:22-24

²²They traveled from Kadesh, and the children of Israel, even the whole congregation, came to Mount Hor.

²³The LORD spoke to Moses and Aaron in Mount Hor, by the border of the land of Edom, saying,

²⁴“Aaron shall be gathered to his people; for he shall not enter into the land which I have given to the children of Israel, because you rebelled against my word at the waters of Meribah.
