Beth-pe'or (Heb. Beyth Peor', בֵּית פִּעוֹר, house of Peor, i.e. temple of Baal-Peor; Sept. οϊvκος Φογώρ, but in Joshua Βηθφογώρ or Βαιθφογώρ), a place in Moab, no doubt dedicated to the god Baal-peor, on the east of Jordan; according to Eusebius and Jerome (Onomast. s.v. Βεθφογόρ, Bethfogo), it lay opposite Jericho, and six miles above Livias or Beth-haran. It was in the possession of the tribe of Reuben (Jos 13:20). In the Pentateuch the name occurs in a formula by which one of the last halting-places of the children of Israel is designated — "the ravine (הִגִּאי) over against (מוּל) Beth-peor" (De 3:29; De 4:46). In this ravine Moses was probably buried (De 34:6). It appears to have been situated on the slope of the eminence (Nebo or Peer), about half way between Heshbon and the north end of the Dead Sea.
Here, as in other cases, the Beth- may be a Hebrew substitution for Baal-, or the name may be an abbreviation of Baal-peor (q.v.).
