Baal-peor. Baal = Lord; Peor was the mountain on which he was worshipped (Num_25:18. Jos_22:17). Baal was a Moabitish idol, and those who called (Num_25:2) the Israelites were the prostitutes necessary for his worship by others. Compare Hos_9:10. Jer_11:13. Peor also means "opening", and may have relation to this "worship".
