King Asa’a wall. A 15-foot-thick wall protected Mizpah during the period of the Divided Monarchy, when the city lay on the border between Israel in the north and Judah in the south. (The figure in the photo is standing on top of the wall remains.) According to the Bible, when King Baasha (906 to 883 B.C.) of Israel invaded Judah, King Asa (908 to 867 B.C.) encouraged the ruler of Damascus to attack Baasha from the north. Baasha fled, leaving behind stones, timber and other supplies that Asa used to fortify Mizpah.
