A precipice, an ancient royal Canaanitish city (Josh. 10:33; 12:12). It was allotted with its suburbs to the Kohathite Levites (21:21; 1 Chr. 6:67). It stood between the lower Beth-horon and the sea (Josh. 16:3; 1 Kings 9:17). It was the last point to which David pursued the Philistines (2 Sam. 5:25; 1 Chr. 14:16) after the battle of Baal-perazim. The Canaanites retained possession of it till the time of Solomon, when the king of Egypt took it and gave it to Solomon as a part of the dowry of the Egyptian princess whom he married (1 Kings 9:15-17). It is identified with Tell el-Jezer, about 10 miles south-west of Beth-horon. It is mentioned in the Amarna tablets.
