1 Samuel 23
6 Ref And it came to pass, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.
7 Ref And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into my hand; for he is shut in, by entering into a town that hath gates and bars.
8 And Saul summoned all the people to war, to go down to Keilah, to besiege David and his men.
9 Ref And David knew that Saul was devising mischief against him; and he said to Abiathar the priest, Bring hither the ephod.
