John Gill Commentary Joshua 13:17

"Heshbon, and all its cities that are in the plain; Dibon, and Bamoth-baal, and Beth-baal-meon," — Joshua 13:17 (ASV)

Heshbon, and all her cities that [are] in the plain
Which was by Medeba, and reached to Dibon:

Dibon, and Bamothbaal, and Bethbaalmeon ;
Dibon was rebuilt by Gad, though it belonged to Reuben, and perhaps was inhabited by both, being on the borders of each; and Bamothbaal signifies the high places of Baal; see (Numbers 22:41) ; perhaps this is the same with Bamoth in the valley, (Numbers 21:20) ; and Bethbaalmeon is the same with Baalmeon in (Numbers 32:38) ; where it is highly probable was a temple of Baal, since both "beth" signifies an house, and "meon" an habitation.
