1 Samuel 23:7-9

Darby Translation

⁷ And it was told Saul that David had come to Keilah. Then Saul said, God has cast him off into my hand; for he is shut in, by entering into a city that has gates and bars.

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

⁹ And when David knew that Saul devised mischief against him, he said to Abiathar the priest, Bring the ephod.
