Matthew Poole and continuators on 1 Samuel 25:39

39 ¶ And when David heard that Nabal was dead, he said, Blessed be the LORD, that hath pleaded the cause of my reproach from the hand of Nabal , and hath kept his servant from evil : for the LORD hath returned the wickedness of Nabal upon his own head. And David sent and communed with Abigail, to take her to him to wife.

How could David rejoyce at the Death of his Enemy? Answ. Although it may be said, that he rejoyced not in Nabal's Death as such, but onely in the declaration of Gods Justice in Punishing so great a Wickedness; which was an honour to God, and a document, and therefore a benefit to Mankind, and so a Publick good, and cause of Joy: yet the matter is not weighty, if we confess, that this was another instance of Humane Infirmity iu Duvid, and that it is not proposed for our Imitation, but for our Caution. Yet it may be further said, That this was not purely an act of Private Revenge, because David was a Publick Person, and Anointed King: and therefore Nabal's Reproach cast upon David above, v. 10, 11. was a Contempt of God, and of his Ordinance, and Appointment; which was vindicated by this remarkable Judgment.

i. e. From the Sin of Bloodshed, and Self-revenge, v. 33.

To wit, Messengers; which he thought fitter than to go himself: partly, because if he had met with a Repulse, it had been less Ignominions; and partly, because he would leave her to her freedom and choice, and would not so much as seem to take her by violence. But this doubtless was not done immediately after Nabal's Death, but in some convenient space of time after it; though such Circumstances be commonly omitted in the Sacred History; which gives onely the Heads, and most Important Passages of things.
