the Lord hath returned the wickedness of Nabal upon his own head - If this was an expression of pleasure, and David’s vindictive feelings were gratified by the intelligence of Nabal’s death, it was an instance of human infirmity which we may lament; but perhaps he referred to the unmerited reproach (1Sa 25:10, 1Sa 25:11), and the contempt of God implied in it.
David sent and communed with Abigail, to take her to wife - This unceremonious proceeding was quite in the style of Eastern monarchs, who no sooner take a fancy for a lady than they dispatch a messenger to intimate their royal wishes that she should henceforth reside in the palace; and her duty is implicitly to obey. David’s conduct shows that the manners of the Eastern nations were already imitated by the great men in Israel; and that the morality of the times which God permitted, gave its sanction to the practice of polygamy. His marriage with Abigail brought him a rich estate.
