1 Samuel 23:8 WEB

⁶  It happened, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.

⁷  It was told Saul that David was come to Keilah. Saul said, God has delivered him into my hand; for he is shut in, by entering into a town that has gates and bars.

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

⁹  David knew that Saul was devising mischief against him; and he said to Abiathar the priest, Bring here the ephod.

¹⁰  Then said David, O Yahweh, the God of Israel, your servant has surely heard that Saul seeks to come to Keilah, to destroy the city for my sake.
