1 Samuel 29:7 Meaning

5Is not this David, of whom they sang one to another in dances, saying, Saul slew his thousands, and David his ten thousands?

6Then 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.

7Wherefore now return, and go in peace, that thou displease not the lords of the Philistines.

8And David said unto Achish, But what have I done? and what hast thou found in thy servant so long as I have been with thee unto this day, that I may not go fight against the enemies of my lord the king?

9And Achish answered and said to David, I know that thou art good in my sight, as an angel of God: notwithstanding the princes of the Philistines have said, He shall not go up with us to the battle.
