Albert Barnes Commentary Jeremiah 48:23

"and upon Kiriathaim, and upon Beth-gamul, and upon Beth-meon," — Jeremiah 48:23 (ASV)

Beth-meon - Meon is probably the Moabite Olympus, and thus Beth-Baal-Meon, the full name of this town (Joshua 13:17), would signify the place where the heavenly Baal was worshipped.
