Bamothbaal(heights of Baal), a sanctuary of Baal in the country of Moab (Joshua 13:17) which is probably mentioned in (Numbers 21:19) under the shorter form of Bamoth, or Bamoth-in-the-ravine (20), and again in (Isaiah 15:2)
International Standard Bible Encyclopedia
BAMOTH; BAMOTH-BAALba'-moth, ba'-moth-ba'-al (bamoth-ba'al, "high places of Baal"): Bamoth is referred to in Numbers 21:19, 20, as a station in the journeyings of Israel North of the Arnon. It is probably the same place as the Bamoth-baal of Numbers 22:41 (Revised Version margin), whither Balak, king of Moab, conducted Balaam to view and to curse Israel. Bamoth-baal is named in Joshua 13:17 as one of the cities given to Reuben. Mesha, on the Moabite Stone, speaks of having "rebuilt" Beth-bamoth.
