1 Samuel 29:6-7

Then Achish called David and said to him, “As the LORD lives, you have been upright, and your going out and your coming in with me in the army are pleasing in my sight; for 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. Now therefore return and go in peace, that you may not displease the lords of the Philistines.”
