Zemaraim

(1.) A town of Benjamin (Josh 18:22); now the ruin, rather two ruins, es-Sumrah, 4 miles north of Jericho.

(2.) A mount in the highlands of Ephraim, to the north of Jerusalem (2Chr 13:4-20). Here the armies of Abijah and Jeroboam engaged in a bloody battle, which issued in the total defeat of the king of Israel, who never "recovered strength again," and soon after died.
