2 Samuel 24:17 Douay-Rheims

And David said to the Lord, when he saw the angel striking the people: It is I; I am he that have sinned, I have done wickedly: these that are the sheep, what have they done? let thy hand, I beseech thee, be turned against me, and against my father’s house.

“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.”

“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?”

“And David spake unto the Lord,.... In prayer; he and the elders of Israel being clothed in sackcloth, and fallen on their faces, he prayed, not unto the angel, but to Jehovah that sent him; see Ch1 21:16, when he saw the angel that smote the people; in the air over Jerusalem, with a drawn sword in his hand, which made him appear terrible: and said, lo, I have sinned, and I have done wickedly; in numbering the people: but these sheep, what have they done? he looked upon himself as the only transgressor, and his people as innocent, and as harmless as sheep; he thought of no sins but his own; these were uppermost in his mind, and lay heavy on his conscience; and it grieved him extremely the his people should suffer on his account: but they were not so innocent as he thought and suggests; and it was not only for his, but their sins, this evil came; he was suffered to do what he did, to bring upon them deserved punishment for their rebellion against him, and other sins; however, this shows the high opinion he had of them, the great affection he had for them, and his sympathy with them in this time of distress: let thine hand, I pray thee, be against me, and against my father's house; let me and mine die, and not they; a type of Christ, the good Shepherd, willing to lay down his life for the sheep, and suffer in their stead, that they might go free.”

“But these sheep, what have they done? - It seems that in the order of Providence there is no way of punishing kings in their regal capacity, but by afflictions on their land, in which the people must necessarily suffer. If the king, therefore, by his own personal offenses, in which the people can have no part, bring down God's judgments upon his people, (though they suffer innocently), grievous will be the account that he must give to God. The people generally suffer for the miscarriages of their governors: this has been observed in every age. Quicquid delirant reges, plectuntur Achivi. - "When doting monarchs urge Unsound resolves, their subjects feel the scourge." Hor. Ep. lib. i., ep. 2, ver. 14. Against my father's house - That is, against his own family; even to cut it off from the face of the earth.”

“Are, like sheep. (Menochius) — They were not accountable for the fault of their shepherd, or king; nor were they punished for it, (Haydock) but for joining in the revolts of Absalom, Seba, &c., (Salien) as well as for other secret offences. (Haydock) — Some groundlessly condemn the people, for entertaining sentiments of pride, along with David. Both king and people suffer, when either draws down the vengeance of heaven.”

“David . . . said--or, "had said," I have sinned . . . but these sheep, what have they done?--The guilt of numbering the people lay exclusively with David. But in the body politic as well as natural, when the head suffers, all the members suffer along with it; and, besides, although David's sin was the immediate cause, the great increase of national offenses at this time had (Sa2 24:1) kindled the anger of the Lord.”
