1 Samuel 25:39

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; it was clearly God's judgment upon the insult offered him by Nabal and ever so much better than the revenge which he himself would have taken; for the Lord hath returned the wickedness of Nabal upon his own head. To David it was like a case in law, in which the Lord had rendered the judicial decision. And David sent and communed with Abigail, to take her to him to wife.
