If I have rewarded evil unto him that was at peace with me He probably means to Saul, when he was peaceable and friendly toward him; for David was charged with evil designs against Saul, before Saul broke out into open enmity against him. Yea I have been so far from doing this that I have done the contrary; I have delivered him When it was in my power to destroy him; that without cause Without any provocation on my part, is mine enemy It is probable that David alludes here to his preserving the life of Saul when he was pressed by his attendants to suffer them to take it away, 1 Samuel 24:6; 1 Samuel 26:8, &c.
