Lebaoth was a town in the Negev desert in Judah (Joshua 15:32). Lebaoth was occupied by the tribe of Simeon, and called Beth-lebaoth (Joshua 19:6). The similar list of Simeonite towns has Beth-biri in this place (1 Chronicles 4:31).
Beth means “house of.” This is certainly a part of the original name. This suggests it was a place of worship of the goddess of the lions (lebaoth). Beth-biri might be another place or just a variant of the list in 1 Chronicles.
