1 Samuel 29:6-7

6Then Achish called David, and said unto him, Surely, as Yhwh liveth, thou hast been upright, and thy going out and thy coming in with me in the army is good in my sight: for I have not found evil in thee since the day of thy coming unto me unto this day: nevertheless the lords favour thee not.1 7Wherefore now return, and go in peace, that thou displease not the lords of the Philistines.2
