1 Samuel 29:6-7

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