Hor
Hor is a mountain on the edge of Edom where Aaron the priest died and was buried. The wilderness narrative reaches it after Kadesh, names it as the place where the high-priestly garments pass from Aaron to Eleazar, and later fixes it as a marker on the northern boundary of the promised inheritance.
The Camp at the Edge of Edom
Israel comes to Hor as a stage on the wilderness route. "And they journeyed from Kadesh: and the sons of Israel, even the whole congregation, came to mount Hor" (Num 20:22). The same itinerary in the chapter-by-chapter list of stations places the camp "in mount Hor, in the edge of the land of Edom" (Num 33:37). Yahweh's word to Moses and Aaron at the site is given the same geographical anchor: "in mount Hor, by the border of the land of Edom" (Num 20:23).
The Death of Aaron
Hor is named, above all, as the place where Aaron's priesthood is transferred and his life ends. The reason is given before the act: "Aaron will be gathered to his people; for he will not enter into the land which I have given to the sons of Israel, because you⁺ rebelled against my mouth at the waters of Meribah" (Num 20:24).
The instruction to Moses is precise. "Take Aaron and Eleazar his son, and bring them up to mount Hor; and strip Aaron of his garments, and put them on Eleazar his son: and Aaron will be gathered [to his people], and will die there" (Num 20:25-26). The execution follows the word exactly: "And Moses did as Yahweh commanded: and they went up into mount Hor in the sight of all the congregation. And Moses stripped Aaron of his garments, and put them on Eleazar his son; and Aaron died there on the top of the mount: and Moses and Eleazar came down from the mount" (Num 20:27-28).
The congregation mourns thirty days: "And when all the congregation saw that Aaron was dead, they wept for Aaron thirty days, even all the house of Israel" (Num 20:29). The retrospective notice in the wilderness itinerary is dated and numbered: "And Aaron the priest went up into mount Hor according to the mouth of Yahweh, and died there, in the fortieth year after the sons of Israel had come out of the land of Egypt, in the fifth month, on the first day of the month. And Aaron was a hundred and twenty and three years old when he died in mount Hor" (Num 33:38-39).
Yahweh's later word to Moses on Mount Nebo holds Hor up as the pattern for Moses' own death: "and die in the mount where you go up, and be gathered to your people, as Aaron your brother died in mount Hor, and was gathered to his people" (Deut 32:50).
Departure from Hor
The journey resumes from the same mountain. "And they journeyed from mount Hor by the way to the Red Sea, to go around the land of Edom: and the soul of the people was much discouraged because of the way" (Num 21:4). The stretch beyond Hor becomes the setting for the next round of wilderness complaint and the bronze serpent.
Hor on the Northern Border
A second use of the name belongs to the survey of the land's boundaries. The northern line is drawn from the Mediterranean inland by way of this same name: "And this will be your⁺ north border: from the great sea you⁺ will mark out for you⁺ mount Hor; from mount Hor you⁺ will mark out to the entrance of Hamath; and the goings out of the border will be at Zedad" (Num 34:7-8). The mountain that marks the end of Aaron's life thus also stands, in the surveyor's terms, at the edge of the inheritance his sons will receive.
