|Easton's Bible Dictionary|
Lord of fortune, or troop of Baal, a Canaanite city in the valley of Lebanon at the foot of Hermon, hence called Baal-hermon (Judges 3:3; 1 Chronicles 5:23), near the source of the Jordan (Joshua 13:5; 11:17; 12:7). It was the most northern point to which Joshua's conquests extended. It probably derived its name from the worship of Baal. Its modern representative is Banias. Some have supposed it to be the same as Baalbec.

ba'-al-gad ba`al gadh; Balagada, Balgad: Joshua in his conquest reached as far north as `Baal-gad in the valley' of Lebanon, under Mount Hermon (Joshua 11:17). This definitely locates it in the valley between the Lebanons, to the West or Northwest of Hermon. It must not be confused with Baal-hermon. Conder thinks it may be represented by `Ain Jedeideh.
