A mountainous ridge southeast of the Plain of Esdraelon, having on each side a valley connecting the great plain with the Jordan valley. The valley northeast of Gilboa is the proper Jezreel; that on the southwest side separates Gilboa from the hills of Samaria. On the eastern part of Gilboa was the town from which it was named, now Jelbon. In this vicinity Saul, and Jonathan were defeated by the Philistines, and died, 1 Samuel 28:4,25 . It is now a dry and barren mountain, 2 Samuel 1:6,21 . Endor lay north from Gilboa, and Beth- shean northeast.
