1 Samuel 29:7-9

Darby Translation

⁷ And now return, and go in peace, that thou displease not the lords of the Philistines.

⁸ And David said to Achish, But what have I done? and what hast thou found in thy servant so long as I have been with thee to this day, that I should not go and fight against the enemies of my lord the king?

⁹ And Achish answered and said to David, I know that thou art acceptable to me, as an angel of God; nevertheless the princes of the Philistines have said, He shall not go up with us to the battle.
