2 Chronicles 14:10

Then Asa went out against him, and they set the battle in array in the valley of Zephathah at Mareshah.

Set the battle in array ... at Mareshah - one of the towns which Rehoboam fortified (2 Chronicles 11:8), near a great southern pass in the low country of Judah (Joshua 15:44). The engagement between the armies took place in a plain near that town, called "the valley of Zephathah," supposed to be the broadway coming down Beit Jibrim toward, Tell-es-Safreh (Robinson's 'Biblical Researches,' 2:, p. 422).
