Then Asa went out against him, and they set the battle in array ... at Mareshah - one of the towns which Rehoboam fortified (2Ch 11:8), near a great southern pass in the low country of Judah (Jos 15:44). The engagement between the armies took place in a plain near the town, called “the valley of Zephathah,” supposed to be the broad way coming down Beit Jibrin towards Tell Es-Safren [Robinson].
