Numbers 34:7,8 - Joseph Benson’s Commentary on the Old and New Testaments

Mount Hor Not that Hor where Aaron died, which was southward, and bordering upon Edom, but another mountain, probably Hermon, or some part of mount Lebanon, which is elsewhere mentioned as the northern border of the land, and which, in regard of divers parts, or by divers people, is called by divers names, and here Hor, which signifies a mountain, by way of eminence. Accordingly we find Lebanon and Hermon joined with the entrance of Hamath, (Joshua 13:5,) as mount Hor is here.
