(breastplate), one of the various names of Mount Hermon, that by which it was known to the Zidonians. (3:9) The use of the name in (Psalms 29:6) (slightly altered in the original--Shirion instead of Sirion) is remarkable.
International Standard Bible Encyclopedia 1915
sir'-i-on (siryon; Sanior): The name of Mt. Hermon among the Phoenicians (De 3:9). It is given as "Shirion" in Ps 29:6 (Hebrew "breastplate" or "body armor"). Here it is named with Lebanon. Sirion therefore probably did not denote a particular part of the Hermon Range, as did Senir, but may have been suggested by the conformation of the range itself, as seen from the heights above the Phoenician coast.
