Baal-hazor, Baal's village, is the place on the border of Ephraim and Benjamin where Absalom held the feast of sheep-shearing when Amnon was assassinated according to 2 Samuel 13:23. It is probably identical with Hazor mentioned in Nehemiah 11:33, now Tell' Asur, 8 km north-east of Bethel. It is also a 1,016 meters high mountain and the highest mountain in the West Bank.
