1 Samuel 29:2-9

2And the lords of the Philistines were proceeding on by hundreds and by thousands, and 1David and his men were proceeding on in the rear with Achish. 3Then the commanders of the Philistines said, “What are these Hebrews doing here?” And Achish said to the commanders of the Philistines, “Is this not David, the servant of Saul the king of Israel, 2who has been with me these days, or rather these years, and 3I have found no fault in him from the day he 4deserted to me to this day?” 4But the commanders of the Philistines were angry with him, and the commanders of the Philistines said to him, “Make the man go back, that he may return 5to his place where you have assigned him, and do not let him go down to battle with us, 6or in the battle he may become an adversary to us. For with what could this man make himself acceptable to his lord? Would it not be with the heads of 7these men? 5Is this not David, 8of whom they sing in the dances, saying, ‘Saul has slain his thousands, And David his ten thousands’?”

6Then Achish called David and said to him, “As the Lord lives, you have been upright, and 9your going out and your coming in with me in the army are pleasing in my sight; 10for I have not found evil in you from the day of your coming to me to this day. Nevertheless, you are not pleasing in the sight of the lords. 7Now therefore return and go in peace, that you may not displease the lords of the Philistines.” 8David said to Achish, “11But what have I done? And what have you found in your servant from the day when I came before you to this day, that I may not go and fight against the enemies of my lord the king?” 9But Achish replied to David, “I know that you are pleasing in my sight, 12like an angel of God; nevertheless 13the commanders of the Philistines have said, ‘He must not go up with us to the battle.’
