1 Samuel 23:7-9

7When it was told Saul that David had come to Keilah, Saul said, “God has 1delivered him into my hand, for he shut himself in by entering a city with double gates and bars.”

8So Saul summoned all the people for war, to go down to Keilah to besiege David and his men.

9Now David knew that Saul was plotting evil against him; so he said to 2Abiathar the priest, “3Bring the ephod here.”
