Meaning: lord of the opening.
This was the name of a false god of the Moabites (Numbers 25:3; 31:16; Joshua 22:17), worshipped by obscene rites. So called from Mount Peor, where this worship was celebrated, the Baal of Peor.
The Israelites fell into the worship of this idol (Numbers 25:3, 5, 18; Deuteronomy 4:3; Psalm 106:28; Hos. 9:10).
