1. A Canaanite city east of Bethel. Abraham pitched his tent in the area shortly after arriving in Canaan, and revisited the place after his sojourn in Egypt (Gen 12:8; 13:3). During the Israelite conquest of Canaan after the fall of Jericho, Joshua, told by his spies that Ai was sparsely inhabited, despatched a small force to attack it. The Israelites suffered an overwhelming defeat and were plunged into despair. Joshua appealed to God and was told that this setback was a punishment for Achan's sin (Josh 7:1-12). As soon as Achan was brought to justice (see ACHAN), Joshua attacked Ai a second time; the city was captured, burnt, and reduced to "a heap forever, a desolation to this day'' (Josh 8:1-29).
Among the exiles returning from Babylon with Zerubbabel were men of Ai and Bethel (Ezra 2:1-2, 28; Neh 7:32).
Ai is identified by most scholars with et-Tell, 1 mile (1.6 km) southwest of the site of Bethel, to the north of Jerusalem. Excavations have uncovered remains of houses, public buildings and fortifications from the Early Bronze Age. The city remained in ruins until the 12th century B.C. The small unfortified Iron Age village at the site may represent the biblical Ai defeated by Joshua following a clash with its inhabitants in the wadi to the north of the site.
2. A city mentioned with Heshbon in Jeremiah's prophecy against the Ammonites. The location is unknown (Jer 49:3).
