REPH'AIM, VAL'LEY OF. " It was one of the landmarks of the land of Judah; named after the Rephaim, or "giants," who at an early period were found on both sides of the Jordan. Comp. Gen 14:5; Deut 3:11-13; Josh 13:12; Lev 17:15. David twice defeated the Philistines in this valley. 2 Sam 5:17-25; 2 Sam 23:13; 1 Chr 11:15-16; 1 Chr 14:9-16. The valley was noted for its fertility. Isa 17:5. Its position as a boundary of Judah would indicate it to have been south of the valley of Hinnom.
" This plain is called Beka'a by the Arabs, and since the sixteenth century an attempt has been made to identify it with the valley of Rephaim. Tobler proposed to identify Rephaim with the Wady der Yasin, to the west-north-west of Jerusalem, but this would contradict the account of Josephus, and the other location is quite generally accepted.
