John Gill Bible Commentary

Now David had said,.... When the messengers returned and told him how they had been used by Nabal; or he "said" (c), or was saying within himself, or to his men, what follows, just as Abigail met him: surely in vain have I kept all that this fellow hath in the wilderness; which shows that lie was in a violent passion, and had Nabal in the utmost contempt and indignation, in that he mentions not his name, only says "this", this man or follow; leaving a blank to be filled up with the most ignominious name and character that could be thought of; and repents that he had taken so much care of his flocks when they were feeding by him in the wilderness: so that nothing was missed of all that pertained unto him; and seems to have wished he had suffered his flocks to have been robbed by the Arabs, or worried by wild beasts, since he had been such an ungrateful wretch to him: and he hath requited me evil for good; he had requited evil to him by denying to send him any of his provisions, and by abusing him and his men with opprobrious language; and this was done in return for the good deeds he had done in protecting his servants and his flocks in the wilderness, and for the good words and respectful message he had sent unto him. (c) "ait", V. L. "dixit", Pagninus, Montanus; "dicebat", Vatablus.
