PEOR
“opening, crack.”
(a) Mount Moab, facing the desert (Num. 23:28). From the top of this summit you could see Shittim and the camp of the Israelites (Num. 24:2).
In the time of Eusebius and Jerome, a mountain that rose opposite Jericho, on the road to Heshbon, above or east of Livias, which today is called Tell er-Rãmeh, was still called Peor.
Thus, Peor must have been one of the peaks of the Abarim chain, near the Wadi Hesbãn.
(b) Moabite divinity, who frequently received the name of Baal-peor (lord of Peor); He received worship on Mount Peor (cf. Num. 25:18; 31:16; Josh. 22:17).
