1 In your kindness, O God, be gracious to me, in your own great pity blot out my transgressions.
John Chrysostom · AD 407 Beloved, let us praise her, through whom we have been saved. Let us love her; let us prefer her to wealth. Let us have a merciful soul apart from wealth. Nothing is more characteristic of a Christian than mercy. There is nothing that unbelievers and all people are so amazed at as when we are merciful.
Desert Fathers · AD 500 Some monks called Euchites, or 'men of prayer', once came to Lucius in the ninth region of Alexandria. He asked them, 'What manual work do you do?' They said, 'We do not work with our hands. We obey St Paul's command and pray without ceasing' (1 Thess. 5:17).
Thomas Aquinas · AD 1274 In the preceding Psalms of this decade, the Psalmist seems to have treated of those things that pertain to the state of the kingdom, whose glory he described and to which he invited others. But now, because the glory of this kingdom has been impeded by sin, he treats of the abolition of sin. Here two things must be considered.
2 Wash me clean of my guilt, make me pure of my sin.
Augustine of Hippo · AD 430 "More and more wash me from mine unrighteousness" [Psalm 51:2]. What is, "More and more wash"? One much stained. More and more wash the sins of one knowing. Thou that hast washed off the sins of one ignorant. Not even thus is it to be despaired of Your mercy. "And from my delinquency purge Thou me." According to the manner in which He is physician, offer a recompense.
Thomas Aquinas · AD 1274 "Wash me yet more." Here he asks for the removal of the uncleanness of guilt. A person who has a well-disposed mind abhors the uncleanness of guilt more than the severity of punishment; and therefore he says, "wash me yet more"; as if to say: I ask that you blot out the punishment; but more than that, I ask that you cleanse the stain. Or, "wash me more" than I understand. Rom.
3 For well I know my transgressions, my sin is ever before me.
Pachomius the Great · AD 348 As the holy old man Pachomius was journeying to his own monastery and had come near the desert called Amnon, legions of demons rose both on his right hand and on his left, some following him and others running in front of him, saying, "Behold the blessed man of God." They were doing this, wishing to sow vainglory in him.
Augustine of Hippo · AD 430 Singing to the Lord, we have asked Him to turn away His face from our sins, and to blot out all our crimes. But you can notice, Brothers, that in the same psalm we have heard: For I acknowledge my iniquity, and my sin is ever before me. However, it is said to God elsewhere: Do not turn away your face from me, to whom we have said: Turn your face away from my sins.
Thomas Aquinas · AD 1274 "Because." Here he confesses his guilt. And first, he confesses the guilt. Second, he shows this confession to be acceptable to God. First, therefore, he confesses the guilt.
4 Against you, only you, have I sinned, and done that which is wrong in your sight: you therefore are just when you speak, and clear when you utter judgment.
Romans · AD 56 What advantage then hath the Jew? or what profit is there of circumcision? Much every way: chiefly, because that unto them were committed the oracles of God. For what if some did not believe? shall their unbelief make the faith of God without effect?
Augustine of Hippo · AD 430 "Against You alone have I sinned, and before You an evil thing have I done" [Psalm 51:4]. What is this? For before men was not another's wife debauched and husband slain? Did not all men know what David had done? [2 Samuel 11:4, 15] What is, "Against You alone have I sinned, and before You an evil thing have I done." Because You alone are without sin.
Thomas Aquinas · AD 1274 "Against you alone have I sinned." Above, the Psalmist set forth the recognition of his own guilt; here he aggravates his guilt; and regarding this he does two things. First, he aggravates it. Second, he sets forth what follows from the aggravation, at "that you may be justified." He aggravates this guilt by comparison to God; and in two ways, as is said in Jer.
5 See! In guilt was I brought to the birth, and in sin did my mother conceive me.
Origen of Alexandria · AD 253 Celsus has not explained how error accompanies the "becoming," or product of generation; nor has he expressed himself with sufficient clearness to enable us to compare his ideas with ours, and to pass judgment on them.
Augustine of Hippo · AD 430 "For, behold, in iniquities I was conceived" [Psalm 51:5]. As though he were saying, They are conquered that have done what thou, David, hast done: for this is not a little evil and little sin, to wit, adultery and man-slaying. What of them that from the day that they were born of their mother's womb, have done no such thing?
Thomas Aquinas · AD 1274 "Behold indeed." Here he sets forth the root of the guilt. The root of all actual guilt is original sin, which is contracted from parents infected with that sin; this infection was in the father of David and in his mother.
6 It’s the innermost truth you desire, give me therefore true wisdom of heart.
Augustine of Hippo · AD 430 "For, behold, truth You have loved: uncertain and hidden things of Your wisdom, You have manifested to me" [Psalm 51:6]. That is, You have not left unpunished even the sins of those whom Thou dost pardon. "Truth You have loved:" so mercy You have granted first, as that You should also preserve truth.
Thomas Aquinas · AD 1274 "The uncertain things." Here he asks for total restoration. And first, he sets forth the hope he has. Second, his petition. And first, he sets forth the benefit received, through which he is raised to hope.
7 Purge me clean with hyssop, wash me whiter than snow.
Ambrose of Milan · AD 397 After this white robes were given to you as a sign that you were putting off the covering of sins and putting on the chaste veil of innocence, of which the prophet said, "Purge me with hyssop, and I shall be cleansed; wash me, and I shall be made whiter than snow." For one who is baptized is seen to be purified according to the law and according to the gospel: according to the…
Augustine of Hippo · AD 430 "You shall sprinkle me," he says, "with hyssop, and I shall be cleansed" [Psalm 51:7]. Hyssop we know to be a herb humble but healing: to the rock it is said to adhere with roots. Thence in a mystery the similitude of cleansing the heart has been taken.
Thomas Aquinas · AD 1274 "You shall sprinkle me with hyssop." Above, the Psalmist commemorated the benefit of God granted to him as to the grace of prophecy, from which he was raised to hope; here he shows what he hoped for from God. And there were two things. First, he hopes for the removal of the evils he had incurred through sin.
8 Fill me with joy and gladness, let the bones you have broken rejoice.
Augustine of Hippo · AD 430 But where is humility from hyssop? Hear what followeth: "To my hearing Thou shall give exultation and gladness, and bones humbled shall exult" (ver. 8). I will rejoice in hearing Thee, not in speaking against Thee. Thou hast sinned, why defendest thou thyself?
Thomas Aquinas · AD 1274 "To my hearing." Here he sets forth how he has hope for the recovery of the goods which he had lost; and there are two: namely, the gift of prophecy and the joy of conscience.
9 Hide your face from my sins, and blot out my guilt altogether.
Augustine of Hippo · AD 430 "Turn Thou away Your face from my sins, and all mine iniquities blot out" [Psalm 51:9]. For now bones humbled exult, now with hyssop cleansed, humble I have become.
Thomas Aquinas · AD 1274 "Turn away." Here he asks for the recovery of innocence. And because he considers that the evil of guilt is in him and the good of grace, he first asks for the removal of evil or sin; second, he asks for the removal of the effect of sin, at "Create in me a clean heart, O God." For sin is removed not in the sense that the sin never existed, but in the sense that the committed si…
10 Create me a clean heart, O God, put a new steadfast spirit within me.
Callistus I of Rome · AD 223 People are in error who think that the priests of the Lord, after a lapse, although they may have exhibited true repentance, are not capable of ministering to the Lord and engaging their honorable offices, even though they may lead a good life thereafter and perform their priesthood correctly.
John Chrysostom · AD 407 It would be better to be defiled with unclean mud than with sins. A person who is defiled with mud can wash it off in a short time and become like one who had never fallen into that mire at all.
Thomas Aquinas · AD 1274 "A clean heart." Above, the Psalmist asked for sin to be removed; here he asks for the effects of sin to be removed, which are two: namely, the defilement of the soul and the disorder of the affections. The first effect occurs because a person is attached to earthly things; hence he asks for cleanness of heart. Mt.
11 Cast me not forth from your presence, withdraw not your holy spirit.
Augustine of Hippo · AD 430 "Cast me not forth from Thy face" (ver. 11). Turn away Thy face from my sins: and "cast me not forth from Thy face." Whose face he feareth, upon the face of the Same he calleth. "And Thy Holy Spirit take not away from me." For in one confessing there is the Holy Spirit. Even now, to the gift of the Holy Spirit it belongeth, that what thou hast done displeaseth thee.
Thomas Aquinas · AD 1274 "Do not cast me from your face, and do not take your Holy Spirit from me." Here he asks for the restoration of grace. And first, he asks for grace itself.
12 Give me back the joy of your help, with a willing spirit sustain me.
Jerome · AD 420 "The one who says, I know him, and does not keep his commandments is a liar, and the truth is not in him. But whoever keeps his word, in him the love of God has been truly perfected.
Augustine of Hippo · AD 430 "Give back to me the exultation of Your salvation" [Psalm 51:12]. "Give back" what I had; what by sinning I had lost: to wit, of Your Christ. For who without Him can be made whole?
Thomas Aquinas · AD 1274 "Restore to me": for grace does two things in a person. One is in respect to higher things, namely, it gives delight, because he who has grace has charity, and he who has charity loves God and possesses him; and he who possesses what he loves rejoices. Therefore, where there is charity, there is joy. Rom.
13 I will teach your ways to transgressors, and sinners shall turn to you.
Augustine of Hippo · AD 430 And what Christ worked in Paul, making him from a persecutor into a preacher, how much this may contribute to human salvation, let the Apostle himself speak that no one conscious of great sins may despair of God's mercy. Human speech, he says, is worthy of full acceptance, because Christ Jesus came into this world to save sinners, among whom I am the first.
Thomas Aquinas · AD 1274 "I will teach." Above, the Psalmist set forth his petitions to God; here he promises recompense. And first, he promises what he will do for God in the present. Second, in the future, at "deal favorably." Regarding the first, he does two things. First, he promises God certain spiritual sacrifices.
14 Save me from blood, O God, and my tongue shall ring out your faithfulness.
Augustine of Hippo · AD 430 "Deliver me from bloods, O God, God of my health" (ver. 14). The Latin translator hath expressed, though by a word not Latin, yet an accuracy from the Greek.
Thomas Aquinas · AD 1274 "Deliver me from bloodguilt." Here he promises the sacrifice of praise; and there are two impediments to this sacrifice. One is the guilt of sin; the other is an interior defect. First, therefore, he asks for the removal of the first impediment.
15 Open my lips, O Lord, and my mouth shall declare your praise.
Augustine of Hippo · AD 430 "O Lord, my lips You shall open, and my mouth shall tell of Your praise" [Psalm 51:15]. "Your praise," because I have been created: "Your praise," because sinning I have not been forsaken: "Your praise," because I have been admonished to confess: "Your praise," because in order that I might be secured I have been cleansed.
Thomas Aquinas · AD 1274 "O Lord, you shall open my lips." It should be known that sometimes a person is impeded from teaching even by an interior impediment to speaking; and this happens sometimes because of the fault of the hearers. Ezek. 3: "I will make your tongue cleave to your palate, and you shall be mute." And below: "Because the house is exasperating." And because of his own sin. Ps.
16 For in sacrifice you have no pleasure, in gifts of burnt-offering no delight.
Thomas Aquinas · AD 1274 "For if you had desired sacrifice." Here he excuses himself. And first, he shows that sacrifice is not acceptable to God; second, he shows what sacrifice is acceptable to God, at "A sacrifice to God." He says therefore: I promise teaching and praise, for this sacrifice will honor you; but carnal sacrifice is not acceptable to you; and therefore he says, "If you had desired sacr…
17 The sacrifice pleasing to God is a spirit that is broken; a heart that is crushed, O God, you will not despise.
Epistle of Barnabas · AD 132 To us, then, He declares, "A sacrifice [pleasing] to God is a broken spirit; a smell of sweet savour to the Lord is a heart that glorifieth Him that made it." We ought therefore, brethren, carefully to inquire concerning our salvation, lest the wicked one, having made his entrance by deceit, should hurl us forth from our [true] life.
Augustine of Hippo · AD 430 Nevertheless, no matter how great our crimes, their forgiveness should never be despaired of in holy Church for those who truly repent, each according to the measure of his sin.
Thomas Aquinas · AD 1274 Hence he adds, "A sacrifice to God," namely one that is acceptable, "is a contrite spirit." Augustine, in City of God 10: Every sacrifice that is offered externally is a sign of an interior sacrifice, in which one offers one's soul to God. But it should be known that the soul of a person is led into sin first through vain joy. Eccl.
18 Do good in your pleasure to Zion, build the walls of Jerusalem.
Augustine of Hippo · AD 430 See who this is: David as one man was seeming to implore; see ye here our image and the type of the Church. "Deal kindly, O Lord, in Your good will with Sion" [Psalm 51:18]. With this Sion deal kindly. What is Sion? A city holy. What is a city holy? That which cannot be hidden, being upon a mountain established.
19 Then will you welcome the due forms of sacrifice, then on your altars shall bullocks be offered.
Augustine of Hippo · AD 430 "Then Thou shalt accept the sacrifice of righteousness" (ver. 19). But now sacrifice for iniquity, to wit, a spirit troubled, and a heart humbled; then the sacrifice of righteousness, praises alone. For, "Blessed they that dwell in Thy house, for ever and ever they shall praise Thee:" for this is the sacrifice of righteousness.
