The mountain on the border of Edom where Aaron died, was stripped of the high-priestly garments in front of his son, and was ‘gathered to his people’ (Numbers 20:22-29). ⚠ It is not securely identified. The long-standing traditional site is Jebel Nebi Harun (‘mountain of the prophet Aaron’) above Petra, which carries a white-domed Muslim shrine to Aaron and has been shown to pilgrims for centuries — but it sits well inside Edom rather than on its border, which is where Numbers puts it, and many scholars prefer Jebel Madurah on the Edom–Negev frontier north-west of Petra. The coordinates given here are the traditional site and are marked approximate. Numbers 33:38 supplies the only date in the wilderness itinerary tied to a death: the first day of the fifth month of the fortieth year. ⚠⚠ There is a SECOND mount Hor, and it is nowhere near this one. Numbers 34:7-8 puts a mount Hor on Canaan's NORTHERN border, on a line drawn from the Mediterranean toward the approach to Hamath — the opposite end of the country from Aaron's mountain on the edge of Edom. The Hebrew is letter for letter the same, Hor ha-Har, 'Hor the mountain', which is really a common noun for a height doing duty as a name, so two unrelated peaks can carry it without contradiction. Searched consonantally the phrase stands in thirteen verses: ten are Aaron's (Numbers 20:22, 23, 25, 27; 21:4; 33:37, 38, 39, 41; Deuteronomy 32:50), two are the northern one, and the thirteenth is not the name at all (Micah 7:12, where the same letters mean 'from mountain to mountain'). ⭐ The Douay-Rheims is the one version on the shelf that never creates the problem, because it declines the name: following the Vulgate's montem altissimum it renders the northern one 'the most high mountain'. The northern Hor is unidentified; the coordinates on this entry are Aaron's.
