one king of Jericho, one king of Ai which was near Bethel,
Then Adonai said to Joshua: “Do not be afraid or dismayed. Take all the people of war with you and arise, go up to Ai. Behold, I have given the king of Ai, his people, his city and his land into your hand.
Not a man was left in Ai or Bethel who did not go out after Israel, so they left the city open as they chased after Israel.
