Surely, as the Lord liveth. — This seems a strange oath for an idolatrous prince like the King of Gath to make use of — “By the life of Jehovah.” It was probably the equivalent of the real oath of Achish, unless, as Keil supposes, the Philistine friend of David, in his oath, used the formula which he thought would be most acceptable to David, whom he looked upon as injured falsely by the suspicion of the Philistine leaders.

6 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 lordsa favour thee not.
