The Philistine officers said, “What are these Hebrews [doing here]?” And Achish replied to the Philistine officers, “Is this not David, the servant of Saul, king of Israel, who has been with me for these days or these years, and I have found no fault with him from the day he encamped [with me] until this very day.”
29:3

But the Philistine officers were angry with him, and the Philistine officers said to him, “Send this man back, and let him return to the place that you assigned to him. Let him not go down to battle with us, so that he not be an antagonist to us in the battle. …
:4

So Achish called David and said to him, “As Hashem lives you are an upright person, and your going forth and coming in with me in the camp would have been fine with me, for I have found nothing wrong with you from the day of your coming to me until this very day; but in the eyes of the governors you are not good.
:6

So now, return, and go in peace, and do not do what is wrong in the eyes of the Philistine governors.”
:7

David then said to Achish, “But what have I done, and what [fault] have you found with your servant from the day I have been before you to this very day, that I should not come and fight against the enemies of my lord the king?”
:8

So Achish answered, and said to David, “I know — for in my eyes you are as good as an angel of God — but the Philistine officers have said, ‘He shall not go up with us into battle.’
:9

1 And the Philistines gathered all their camps to Aphek, and the Israelites were encamped by the fountain which is in Jezreel.
2 And the lords of the Phillistines were passing on by hundreds and by thousands, and David and his men were passing in the rear with Achish.
3 And the officers of the Philistines said, “What are these Hebrews (doing here)?” And Achish said to the officers of the Philistines, “Is this not David, the servant of Saul the king of Israel, who has been with me these days or these years, and I have found no fault in him from the day he fell (in with me) until this day.”
4 But the officers of the Philistines were enraged against him, and the officers of the Philistines said to him, “Return the man, and let him return to his place, where you have appointed him, and let him not go down with us into the battle, lest he become an adversary to us in the battle. And with what will this one reconcile himself to his master? Is it not with the heads of those men?
5 Is this not David of whom they sang with musical instruments, saying, ‘Saul has slain his thousands and David his ten thousands.’ “
6 And Achish called to David and said to him, “As the Lord lives, (I swear) that you are upright, and your going out and coming in with me in the camp, is good in my eyes, for I have not found in you any evil from the day of your coming to me until this day, but you are not good in the eyes of the lords.
7 And now, return and go peacefully, and do not do evil in the eyes of the lords of the Philistines.”
8 And David said to Achish, “But what have I done and what have you found in your bondsman until this day, that I shall not come and wage war against the enemies of my lord the king?”
9 And Achish answered and said to David, “I know that you are good in my eyes like an angel of God, but the officers of the Philistines have said, ‘Let him not go up with us into the battle.’
10 And now, arise early in the morning with your master’s bondsmen who came with you, and you shall arise early in the morning when it is light for you, and go.”
11 And David arose early, he and his men to go in the morning to return to the land of the Philistines; and the Philistines went up to Jezreel.
