Numbers 34:7 - Matthew Poole's English Annotations on the Holy Bible

Not that Hor where Aaron died, Numbers 20:23, which was southward, and bordering upon Edom, Numbers 33:37,38, and therefore could not be their northern border; but another mountain, and, as it is conceived, the mountain of Libanus, 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, as Sirion and Shenir, Deuteronomy 3:9, and Sion, Deuteronomy 4:48, and Hermon, Joshua 13:5, and here Hor, which signifies a mountain, and this may be called so by way of eminency. Certain it is, that as Hor here, so Hemon, Joshua 13:5, is joined with the entrance of Hamath, which makes it probable they are one and the same place.
