|Easton's Bible Dictionary|
Lord of Hermon.
(1.) A city near Mount Hermon inhabited by the Ephraimites (1 Chronicles 5:23). Probably identical with Baal-gad (Joshua 11:17).
(2.) A mountain east of Lebanon (Judges 3:3). Probably it may be the same as Mount Hermon, or one of its three peaks.
Int. Standard Bible Encyclopedia
ba'-al-hur'-mon ba`al chermon; Baal Ermon: Baalgad under Mount Hermon is described as "toward the sunrising" in Joshua 13:5. If Mount Lebanon proper is here intended the reading may be taken as correct. But in Judges 3:3 Baal-gad is replaced by Baal-hermon. One or the other must be due to a scribal error. The Baal-hermon of 1 Chronicles 5:23 lay somewhere East of the Jordan, near to Mount Hermon. It may possibly be identical with Banias.
