C. F. Keil and Franz Delitzsch on 1 Samuel 29:8-9

1Sa 29:8-9

Partly for the sake of vindicating himself against this suspicion, and partly to put the sincerity of Achish’s words to the test, David replied, “What have I done, and what hast thou found in thy servant, since I was with thee till this day, that I am not to come and fight against the enemies of my lord the king?” These last words are also ambiguous, since the king whom David calls his lord might be understood as meaning either Achish or Saul. Achish, in his goodness of heart, applies them without suspicion to himself; for he assures David still more earnestly (1Sa 29:9), that he is firmly convinced of his uprightness. “I know that thou art good in my eyes as an angel of God,” i.e., I have the strongest conviction that thou hast behaved as well towards me as an angel could; but the princes have desired thy removal.
