Then the Lord spoke to Moses and Aaron at Mount Hor, by the border of the land of Edom, saying,
“Aaron will be gathered to his people [in death]; for he shall not enter the land which I have given to the children of Israel, because you [both] rebelled against My command at the waters of Meribah. [Num 20:7-12]
They moved out from Kadesh and camped at Mount Hor, on the edge of the land of Edom.
