SION sī’ un (שִׂיאֹ֖ן ; Σηών, lofty). 1. One of several designations of Mt. Hermon (Deut 4:48 KJV). 2. KJV for Zion (Ps 65:1). 3. The Gr. form of the Heb. Zion in the NT. International Standard Bible Encyclopedia (1915) (si’on; Seon): (1) A name given to Mt. Hermon in De 4:48. The name may mean "protuberance" or "peak," and may have denoted the lofty snow-covered horn of the mountain as seen from the South. It may, however, be a scribal error for Sirion, the name by which the mountain was known to the Zidonians. Syriac takes it in this sense, which, however, may be a correction of the Hebrew. It is possible that this name, like Senir, may have applied to some distinct part of the Hermon Range. (2) Mt. Sion. See [[Zion]].
