Hor

Mount Hor is most prominently the mountain on the border of Edom where Aaron the high priest died and was buried. Numbers 20:22–29 records that God commanded Moses and Aaron to go up to Mount Hor, where Aaron's priestly vestments were transferred to his son Eleazar before Aaron died on the summit at age 123. Israel mourned Aaron for thirty days. The precise identification of Mount Hor remains disputed; the traditional identification with Jebel Harun (Aaron's Mountain) above Petra in modern Jordan is ancient but not universally accepted by scholars.

A second Mount Hor is mentioned in Numbers 34:7–8 as a landmark on the northern boundary of Canaan, apparently located near the Mediterranean coast in the direction of the entrance to Hamath—a entirely different location from the Edomite Hor. The repetition of the name thus represents two different mountains, the southern one associated with Aaron's death and the northern one serving as a geographic marker for the tribal boundaries. The name Hor may simply mean mountain or hill in a general sense.
