1 Samuel 23:7-9

Someone told Saul that David was now at Keilah. Saul said, “God has handed David over to me! He has trapped himself, because he has entered a town with gates and bars.” Saul called all his army together for battle, and they prepared to go down to Keilah to attack David and his men. David learned Saul was making evil plans against him. So he said to Abiathar the priest, “Bring the holy vest.”
