1 Samuel 23:6-8

Young's Literal Translation

⁶ And it cometh to pass, in the fleeing of Abiathar son of Ahimelech unto David, to Keilah, an ephod came down in his hand.

⁷ And it is declared to Saul that David hath come in to Keilah, and Saul saith, `God hath made him known for my hand, for he hath been shut in, to enter into a city of doors and bar.'

⁸ And Saul summoneth the whole of the people to battle, to go down to Keilah, to lay siege unto David and unto his men.
