1 Samuel 29:3

1Now the Philistines gathered together all their armies to Aphek; and the Israelites encamped by the spring which is in Jezreel.

2The lords of the Philistines passed on by hundreds and by thousands; and David and his men passed on in the rear with Achish.

3Then the princes of the Philistines said, “What about these Hebrews?” Achish said to the princes of the Philistines, “Isn’t this David, the servant of Saul the king of Israel, who has been with me these days, or rather these years? I have found no fault in him since he fell away until today.”

4But the princes of the Philistines were angry with him; and the princes of the Philistines said to him, “Make the man return, that he may go back to his place where you have appointed him, and let him not go down with us to battle, lest in the battle he become an adversary to us. For with what should this fellow reconcile himself to his lord? Should it not be with the heads of these men?

5Isn’t this David, of whom people sang to one another in dances, saying, ‘Saul has slain his thousands, and David his ten thousands’?”
