the king of Jericho, the king of Ai (near Bethel),
The Lord said to Joshua, “Don’t be terrified or afraid. Take all the troops with you, and march against Ai. I am about to hand the king of Ai, his people, city, and land over to you.
Not one man was left in Ai or Bethel; they all went after Israel. So the city was left unprotected as they chased Israel.
