The term is a compound noun, with 'Baal' meaning 'lord' and 'Zebub' meaning 'flies'.
Cultural context
Baal-Zebub was a deity worshiped in Ekron, a Philistine city. The name is likely a derogatory alteration of 'Baal-Zebul' (Lord of the High Place), reflecting Israel's disdain for foreign gods.
Theological significance
The invocation of Baal-Zebub by King Ahaziah highlights Israel's apostasy and reliance on foreign gods, contrasting with the worship of Yahweh.
