HERMON, or AERMON (anc. geog.); a mountain of the Amorites, called Sanior by the Phoenicians, and Sanir or Senir by the Amorites on the east of Jordan. It is also called Sion, (Moses); but must not be confounded with the Sion of Jerusalem. By the Sidonians it was called Seirion; in the vulgate, it is called Sarion. Joshua informs us, that it was the dominion of Og king of Bashan; which must be understood of its south side. It is never particularly mentioned by profane writers; being comprised under the appellation Libanus, or Antilibanus, with which mountain it is joined to the east. It is also called Hermonim plurally, Psalm xlii. 6. because it was extensive, and contained several mountains.
