1 Samuel 29:3-5

New Catholic Bible

³ The lords of the Philistines said, “What about these Hebrews?” Achish replied to the lords of the Philistines, “Is this not David, a servant of Saul, the king of the Israel? He has been with me these days, these years. I have found no fault in him since he came to me up until the present.”

⁴ The lords of the Philistines were angry with him, and the lords of the Philistines said to him, “Send that man back, let him go back to the place where you have assigned him. Do not let him go into battle with us, lest he turn against us during the battle. What other way could he reconcile to his master if not with the heads of these men? ⁵ Is this not the David of whom they sang while they were dancing, ‘Saul has killed his thousands, and David has killed his ten thousands.’ ”
