I Samuel 25:39

"So when David heard that Nabal was dead, he said, 'Blessed be the Lord, Who has pleaded the cause of my reproach from the hand of Nabal, and has kept His servant from evil! For the Lord has returned the wickedness of Nabal on his own head.' And David sent and proposed to Abigail, to take her as his wife."

("Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, 'Vengeance is Mine, I will repay,' says the Lord." Romans 12:19)
