Ambrose of Milan : But before this David had already held back his armed hand in his indignation. How much greater it is not to revile again, than not to avenge oneself! The warriors, too, [who] prepared to take vengeance against Nabal, Abigail restrained by her prayers. From this we perceive that we ought not only to yield to timely entreaties but also to be pleased with them. So much was David pleased that he blessed her who intervened, because he was restrained from his desire for revenge. — On the Duties of the Clergy 1.21.94 Bede : When Abigail saw David, she hastened and descended from the donkey, etc. When the synagogue recognized Christ, or rather, having itself been recognized by Christ, it hastened to renounce its old way of life, which had zeal for God, but not according to knowledge; and with the most devout humility, bearing witness to itself as dust and ashes, it began to worship the steps of the Lord's incarnation with humble prayer, either repenting for itself to be accepted by the Lord, or praying for its people and unbelieving leaders that they may not be struck corporally, with an open confession, and testifying that the wicked are reserved for eternal punishment, and that Christ's kingdom will remain in perpetual peace, and begging with every desire of the soul that it may belong to this. — Commentary on Samuel
