Sir'ion (Heb. Siryon', ]שַׂרוֹ, in Deuteronomy, but in Psalm 29 Shiryon', שַׁריוֹ; Samar'. שרין; Samuel Ver. רב; Sept. Σανιώρ; Vulg. Sarion), one of the various names of Mount HERMON SEE HERMON (q.v.), that by which it was known to the Zidonians (De 3:9). The word is almost identical with that (סרין) which in Hebrew denotes a breastplate, or "cuirass;" and Gesenius therefore expresses his belief that it was applied in this sense to the mountain just as the name Thorax (which has the same meaning) was given to a mountain in Magnesia. This is not supported by the Samuel Ver., the rendering in which –Rabban — seems to be equivalent to Jebel esh-Sheik, the ordinary, though not the only modern, name of the mountain.
