1 Be favorable unto me, O God, according to thy lovingkindness, And, in the multitude of thy compassions, blot out my transgressions;
Ambrosiaster · AD 384 ON PSALM FIFTY. — The Fiftieth Psalm is placed here not according in chronological order, but according to rationale. For its title is governed not by number, but by meaning. As far as history is concerned, it comes before the third. For the prophet Nathan rebuked him for his sin before his son Absalom rose up against him to deprive him of both life and kingdom.
Augustine of Hippo · AD 430 Hear therefore these words, and say thou with him: "Have pity upon me, O God, after Thy great mercy" [Psalm 51:1]. He that imploreth great mercy, confesseth great misery. Let them seek a little mercy of Thee, that have sinned in ignorance: "Have pity," he saith, "upon me, after Thy great mercy." Relieve a deep wound after Thy great healing.
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 Thoroughly wash me from mine iniquity, And, from my sin, make me pure;
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, my transgressions, do, I, acknowledge, And, my sin, is before me continually:
Origen of Alexandria · AD 253 He too who has sinned, and after the sin remembers that he has sinned, ought to say these things, just as David himself said in the fiftieth psalm: "And my sin is ever before me." There are certain people who, when they have sinned, are utterly secure, and do not think about their sin, nor does it come to their senses what evil they have done, but they live as though they had c…
Augustine of Hippo · AD 430 "For mine iniquity I acknowledge, and my delinquency is before me ever" (ver. 3). I have not put behind my back what I have done, I look not at others, forgetful of myself, I pretend not to pull out a straw from my brother's eye, when there is a beam in my eye; my sin is before me, not behind me.
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 thee—against thee alone, have I sinned, And, wickedness—in thine eyes, have I done,—That thou mayest, Be justified when thou speakest,—Be clear when thou judgest.
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 Lo! in iniquity, was I brought forth, And, in sin, did my mother conceive me.
Origen of Alexandria · AD 253 But if it pleases you to hear what the other saints also thought concerning that nativity, hear David saying: "In iniquities," he says, "was I conceived, and in sins did my mother bear me," showing that whatever soul is born in the flesh is polluted with the filth "of iniquity and sin"; and that on this account was said what we have already mentioned above, that: "No one is cle…
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 Lo! faithfulness, hast thou desired in the inward parts, Yea, in the hidden part, wilt thou cause me to know, wisdom.
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 "Behold, you have loved truth." He who wishes to make satisfaction must love the things that God loves. But God loves the truth of faith. Jn. 18: "Everyone who is of the truth hears my voice." Also, justice. Ps. 88: "Mercy and truth shall go before your face." And this is necessary in the penitent, that he punish in himself what he has done wrong.
7 Wilt thou cleanse me from sin with hyssop, That I may be pure? Wilt thou wash me, That I may be 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 Wilt thou cause me to hear joy and gladness? The bones thou hast crushed would exult.
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 thy face from my sins,—And, all mine iniquities, blot out;
Augustine of Hippo · AD 430 So all past sins are forgiven people on conversion; but for the rest of this life there are certain grave and deadly sins, from which one can be released only by the most vehement and distressing humbling of the heart and contrition of spirit and the pain of repentance. These are forgiven through the keys of the church.
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 A pure heart, create for me, O God, And, a steadfast spirit, renew 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 Do not cast me away from thy presence, And, thy Holy Spirit, do not take from me:
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 Restore unto me the joy of thy salvation, And, with a willing spirit, wilt thou uphold 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 would teach transgressors thy ways, And, sinners, unto thee, should return.
Augustine of Hippo · AD 430 But see what he annexeth: "With Principal Spirit," he saith, "confirm Thou me." Wherein "confirm"? Because Thou hast pardoned me, because I am secure, that what Thou hast forgiven is not to be ascribed, on this being made secure and with this grace confirmed, therefore I am not ungrateful. But I shall do what? "I would teach unrighteous men Thy ways" (ver. 13).
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 Rescue me from shed-blood, O God, the God of my salvation, My tongue should shout thy righteousness;
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 O My Lord! my lips, wilt thou open, And, my mouth, shall declare thy 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 thou wilt not desire sacrifice—that I should give it, Ascending-offering, will not please:
Ambrosiaster · AD 384 WHY IS IT THAT IN THE LAW EVEN AARON HIMSELF IS TOLD THAT HE MUST OFFER BURNT OFFERINGS FOR HIS SINS, WHEN DAVID SAYS, “FOR FAULTS YOU HAVE NOT REQUIRED A BURNT OFFERING” (Ps. 39:7), AND LATER, “YOU WILL NOT TAKE PLEASURE IN BURNT OFFERINGS” (Ps. 50:18)? HOW DID HE COMMAND THAT THERE BE OFFERED WHAT HE DOES NOT TAKE PLEASURE IN?
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 sacrifices of God, are a spirit that is broken,—A heart—broken and crushed, O God, thou wilt 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 Do you wish to appease God? Know what you do with yourself, so that God may be appeased with you. Note in the same psalm; for it is read there: Because if you had desired sacrifice, I would indeed have given it; with burnt offerings you will not be delighting. Therefore will you be without sacrifice? Will you offer nothing, appeasing God with no offering? What did you say?
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 thy good-pleasure, unto Zion, Wilt thou 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, shalt thou desire the sacrifices of righteousness, Ascending-sacrifice and whole burnt-offering, Then, shall ascend upon thine altar, young bulls.
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.
