1 Samuel 29:4-6

29:4 But the leaders of the Philistines became angry with him and said to him, “Send the man back! Let him return to the place that you assigned him! Don’t let him go down with us into the battle, for he might become our adversary in the battle. What better way to please his lord than with the heads of these men? 29:5 Isn’t this David, of whom they sang as they danced,

‘Saul has struck down his thousands,

but David his tens of thousands’?”

29:6 So Achish summoned David and said to him, “As surely as the Lord lives, you are an honest man, and I am glad to have you serving with me in the army. I have found no fault with you from the day that you first came to me until the present time. But in the opinion of the leaders, you are not reliable.
