1 Samuel 29:3

3 Then the princes of the Philistines said, What [are] these Hebrews [doing here]? And Achish said to the princes of the Philistines, Isn't this David, the slave of Saul the king of Israel, who has been with me these days, or [rather] these years, and I have found no fault in him since he fell away [to me] to this day?
