Verse 8. - Hermon (חֶרְמון), probably from חָרַם, to be high, "the lofty peak," conspicuous on all sides. By some the name is supposed to be connected with חֶרֶם, a devoted thing, because this mountain marked the limit of the country devoted or placed under a ban; and it is certainly remarkable that, at the extreme north-east and the extreme southwest of the laud conquered by the Israelites, names derived from Hereto, viz. Hermon and Hormah (Deuteronomy 1:44), should be found; as if to indicate that all between was devoted. Hermon is the southernmost spur of the Autilibanus range. It is "the second mountain in Syria, ranking next to the highest peak of Lebanon behind the cedars. The elevation of Hermon may be estimated at about 10,000 feet. The whole body of the mountain is limestone, similar to that which composes the main ridge of Lebanon, the central peak rises up an obtuse truncated cone, from 2000 to 3000 feet above the ridges that radiate from it, thus giving it a more commanding aspect than any other mountain in Syria. This cone is entirely naked, destitute alike of trees and vegetation. The snow never disappears from its summit" (Porter, 'Handbook, Syria and Palestine,' p. 431). At the present day it is known as Jebel esh-Sheikh (The Chief Mountain), also Jebel eth Thel (The Snow Mountain). Anciently also it had various names. By the Hebrews it was known also as Sion (שִׂיאֹן, the high, Deuteronomy 4:48); by the Sidonians it was called Sirion (שִׂרְיון = שִׁרְיון, a cuirass or coat of mail), probably from its shining appearance, especially when covered with snow and by the Amorites it was called Senir, a word probably of the same meaning. These names continued in use to a late period (cf. Psalm 99:6; Ezekiel 27:4; Song of Solomon 4:8; 1 Chronicles 5:23).

3:1-11 Og was very powerful, but he did not take warning by the ruin of Sihon, and desire conditions of peace. He trusted his own strength, and so was hardened to his destruction. Those not awakened by the judgments of God on others, ripen for the like judgments on themselves.br>And we took at that time out of the hands of the two kings of the Amorites,.... Sihon king of Heshbon, and Og king of Bashan:

the land that was on this side Jordan; where Moses then was, being in the plains of Moab, and was the country beyond Jordan, with respect to the land of Canaan, and when in that:

from the river of Arnon unto Mount Hermon; Arnon was a river which divided Moab and the Amorites, Numbers 22:13 and Hermon was a mountain of Gilead, which ended where Lebanon began, and was the northerly border of this country. It was remarkable for the dew that fell on it; See Gill on Psalm 133:3.
