Mt. Hermon
A noble mountain on the north-east border of Palestine, forming the highest part of the Anti-Lebanon range. Its highest summit is 9,200 feet above the sea, and is almost constantly covered with snow. It was called by the Sidonians SIRION (Deut. 3:99(Which Hermon the Sidonians call Sirion; and the Amorites call it Shenir;) (Deuteronomy 3:9); Psa. 29:66He maketh them also to skip like a calf; Lebanon and Sirion like a young unicorn. (Psalm 29:6)); and SHENIR by the Amorites (or perhaps one of the summits was called SHENIR or SENIR (1 Chron. 5:2323And the children of the half tribe of Manasseh dwelt in the land: they increased from Bashan unto Baal-hermon and Senir, and unto mount Hermon. (1 Chronicles 5:23); Song of Sol. 4:88Come with me from Lebanon, my spouse, with me from Lebanon: look from the top of Amana, from the top of Shenir and Hermon, from the lions' dens, from the mountains of the leopards. (Song of Solomon 4:8); Ezek. 27:55They have made all thy ship boards of fir trees of Senir: they have taken cedars from Lebanon to make masts for thee. (Ezekiel 27:5)); and once it was called SION (Deut. 4:4848From Aroer, which is by the bank of the river Arnon, even unto mount Sion, which is Hermon, (Deuteronomy 4:48)). The silent refreshing dews of Hermon are used to illustrate how good and pleasant it is for brethren to dwell together in unity (Psa. 133:33As the dew of Hermon, and as the dew that descended upon the mountains of Zion: for there the Lord commanded the blessing, even life for evermore. (Psalm 133:3)). It is probable that some part of Hermon was the mount of transfiguration; the Lord was in that district, and it seems much more suitable from its privacy than the traditional mount Tabor. It is now called Jebel esh Sheikh, or Jebel eth Thelj, “mountain of snow” 33° 25' N, 35° 51' E.
