A city of Moab condemned in Jeremiah's oracle against Moab (Jeremiah 48:23). The name combines bayit (house) with gamul, from gamal (H1580), meaning to wean, deal bountifully, or recompense.
The oracles against the nations in Jeremiah and other prophets remind Israel — and all readers — that no nation exists outside God's sovereign judgment. Moab, though descended from Lot and thus related to Abraham's family, had become a place of pride and idolatry. The prophetic judgment on Beth-Gamul declares that places built on false confidence in earthly power will fall. The name's double meaning (weaned/recompensed) carries prophetic irony: those who thought themselves mature and self-sufficient would receive the recompense their deeds deserved.
