ba-al-pe-ra'-zim, ba-al-per'-azim ba`al peratsim; Baal'pharasein, ("the lord of breakings through"): The spot in or near the Valley of Rephaim where David obtained a signal victory over the Philistines; it was higher than Jerusalem for David asked, "Shall I go up against the Philis?" (2 Samuel 5:20 1 Chronicles 14:11). The exact site is unknown, but if the Vale of Rephaim is el Beka`a, the open valley between Jerusalem and Mar Elias, then Baal-perazim would probably be the mountains to the East near what is called the "Mount of Evil Counsel" (see JERUSALEM). The Mount Perazim of Isaiah 28:21 would appear to be the same spot.
