2Sam 24:17

“He is a most diligent pastor who delivered over himself on behalf of his sheep. He is an excellent leader who gave himself in behalf of his sheep.… And when David numbered the flock of his sheep, wrath came upon them, and they began to be destroyed. Then David delivered himself over on behalf of his sheep, when he prayed, saying, "O Lord God, I have sinned in that I have numbered Israel. Let your hand be on me and on my father's house. These innocent sheep, how have they sinned?" So also [in this way] all the diligent pastors used to give themselves on behalf of their sheep.But those pastors who did not care for the sheep, those were hirelings who used to feed themselves alone.”

“Good, therefore, is humility. It delivers those who are in danger and raises those who have fallen. This humility was known to him who said, "Behold, it is I that have sinned, and I the shepherd have acted wickedly; and these in this flock, what have they done? Let your hand be against me." Well does David say this who made his kingdom subject to God and did penance and, having confessed his sin, asked pardon. He attained salvation through humility. Christ humbled himself to raise up all, and whoever follows the humility of Christ attains the rest of Christ.”

“Therefore since the apostle taught that a person who has passed out of this body will be with Christ, provided he deserves it, let us consider the nature of life and of death. We know from the teaching of Scripture that death is a freeing of the soul from the body, a kind of separation in man. For we are freed from this bond between soul and body, when we depart.… He [David] readily offered himself to death to atone for his offense against the Lord and presented himself, prepared to suffer God's vengeance for the well-being of his afflicted people. He knew that it was more glorious to die for Christ than to rule in this world, for what is more excellent than to become a victim for Christ?”

“And how is it possible (you say) that one should so love his neighbor as himself? If others had not done this, you might well think it impossible: but if they have done it, it is plain that from indolence it is not done by ourselves.And besides, Christ enjoins nothing impossible, seeing that many have even gone beyond his commands. Who has done this? Paul, Peter, all the company of the saints. No, indeed if I say that they loved their neighbors, I say no great matter: they so loved their enemies as no one would love those who were likeminded with himself. For who would choose for the sake of those likeminded to go away into hell when he was about to depart into a kingdom? No one. But Paul chose this for the sake of his enemies, for those who stoned him, those who scourged him. What pardon then will there be for us, what excuse, if we shall not show toward our friends even the very smallest portion of that love which Paul showed toward his enemies? And before him too, the blessed Moses was willing to be blotted out of God's book for the sake of his enemies who had stoned him. David also when he saw those who had stood up against him slain, said, "I, the shepherd, have sinned, but these, what have they done?" And when he had Saul in his hands, he would not slay him but saved him; and this when he himself would be in danger. But if these things were done under the old [covenant], what excuse shall we have who live under the new and do not attain even to the same measure with them? For … "unless our righteousness exceed that of the scribes and Pharisees, we shall not enter into the kingdom of heaven," how shall we enter in when we have even less than they?”
