2Sam 2:22

“But when the passionate so attack others that they cannot be altogether shunned, they should be smitten, not with open rebuke, but sparingly with a certain respectful cautiousness. And this we shall shew better if we bring forward what was done by Abner. For, when Asahel attacked him with the violence of inconsiderate haste, it is written, "Abner spake unto Asahel, saying. Turn thee aside from following me, lest I be driven to smite thee to the ground. Howbeit he scorned to listen, and refused to turn aside. Whereupon Abner smote him with the hinder end of the spear in the groin, and thrust him through, and he died." For of whom did Asahel present a type but of those whom fury violently seizes and carries headlong? And such, in this same attack of fury, are to be shunned cautiously in proportion as they are madly hurried on. Whence also Abner, who in our speech is called the lantern of the father, fled; because when the tongue of teachers, which indicates the supernal light of God, sees the mind of any one borne along over the steeps of rage, and refrains from casting back darts of words against the angry person, it is as though it were unwilling to smite one that is pursuing. But, when the passionate will not pacify themselves by any consideration, and, like Asahel, cease not to pursue and to be mad, it is necessary that those who endeavour to repress these furious ones should by no means lift themselves up in fury, but exhibit all possible calmness; and yet adroitly bring something to bear whereby they may by a side thrust prick the heart of the furious one. Whence also Abner, when he made a stand against his pursuer, pierced him, not with a direct stroke, but with the hinder end of his spear. For to strike with the point is to oppose with an onset of open rebuke: but to smite the pursuer with the hinder end of the spear is calmly to touch the furious one with certain hits, and, as it were, by sparing him overcome him. Asahel moreover straightway fell, because agitated minds, when they feel themselves to be spared, and yet are touched inwardly by the answers given in calmness, fall at once from the elevation to which they had raised themselves. Those, then, who rebound from the onset of their heat under the stroke of gentleness die, as it were, without steel.”
