Then Achish called David, and said unto 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 since the day of thy coming unto me unto this day: nevertheless the lords favour thee not. Thou hast been upright - So he thought, for as yet he had not heard of the above transaction; David having given him to understand that he had been fighting against Israel.
