I am, I am he that blot out thy iniquities for my own sake, and I will not remember thy sins.

“We must always have these sins before our eyes, so we may be purified from them. And though God, by clemency, forgives you every sin, yet you, for the safety of your soul, must always have the sin before your eyes. For the memory of past sins hinders future ones; and one who is bitten by his past sins demonstrates the will to be steadfast about the next ones. For David says, "And my sin is ever before me," in order to have the past ones before his eyes and not to fall into future ones. That God demands this firm stance from us, listen to him say, "I am the one who blots out your sins, and I will not remember them; you, however, remember them, and we shall settle accounts, says the Lord. First state your sin so you may be justified." … Time does not excuse; rather, the manner of the repentant individual erases the sin.”

“All truth is justice. In the confessing of what is the case, there is justice. He speaks the truth, that sinners who justify themselves by their faults cannot be justified. And in this way one is called truly just in that confessing one's own sin, he asks them to be accounted to himself yet begs God for mercy. For he knows that it is stated in the law, "Confess your sins, and you will be justified." What does it mean "to confess at the start of speaking" unless "to speak freely and not just when forced to"? For who (even one who fears God) is without sin, since faults get mixed into thinking and unconsciously we sin in so many ways?”

“"Forgive us our debts as we also forgive our debtors." Whoever then desires to obtain forgiveness of his sins, should study to fit himself for it by these means. Let not the stubbornness of an obdurate heart turn away any from the saving remedy and the fount of so much goodness, because even if we have done all these things, they will not be able to expiate our offences, unless they are blotted out by the goodness and mercy of the Lord, who when He sees the service of pious efforts offered by us with a humble heart, supports our small and puny efforts with the utmost bounty, and says: "I even I am He that blotteth out thine iniquities for Mine own sake, and I will remember thy sins no more."”

“And now thus says the Lord, etc. Here he shows them the divine love through the remedies which he granted them amid their distresses. And it is divided into three parts. In the first he promises future remedies, to show his love; in the second he recalls past benefits, to confirm the promise: "thus says the Lord, who gave," etc.; in the third he excludes merits, to take away presumption: "you did not call upon me," etc. Concerning the first he does three things. First he shows toward them the privilege of divine love; second, from the promised remedies, he excludes any partnership in divine power: "all the nations are gathered together," etc.; in the third he sets forth the sign of his love: "thus says the Lord your redeemer," etc. Concerning the first, he promises them three remedies. First, sustenance in punishments, excluding fear by the divine presence: "creating you" — as to the principles of substance, Deut. 32: "he is your father," etc.; "forming" — as to the form which he gave, Gen. 1: "the Lord formed," etc.; "redeeming" — from evils, Hosea 13: "from the hand of death," etc.; and "I have called" — unto grace, Hosea 1: "I will call 'not my people,'" etc. He sets forth the promise: "when you shall pass through the waters" — the Egyptians; "the rivers" — the Chaldeans; "the fire" — the Greeks; "the flame" — the Romans. For they were not consumed entirely. Ps. 65: "we passed through fire," etc. And he assigns the reason for this: "for I am the Lord," etc., above, 12: "for he himself, God, is savior," etc. Second, he promises a commutation of punishments, namely that he will punish others in his place. And he sets forth the commutation. "I have given a propitiation" — that is, that I might be propitiated toward you, as it were by the punishments of those who provoked you to sin by the hope of their help. "Saba" — a city of Ethiopia. Prov. 11: "the just man out of distress," etc. And he assigns the reason, namely God's own love: "since you have become honorable" — that is, I have made and accounted you honorable. "For you" — for your liberation. Jer. 31: "if a son honorable to me," etc. Third, he promises them liberation of every kind from tribulations; and concerning this, three things. First he promises the benefit of liberation: "do not fear, from the east" — because they had been scattered in every direction. Above, 11: "he will gather the fugitives," etc.; Jer. 31: "behold I will bring them," etc. Second, he sets forth the merit of liberation: "and everyone who calls upon me I will bring" — "unto my glory," that he may glorify me, and I may appear glorious in him. Joel 2: "everyone whosoever shall call upon," etc. Third, he promulgates the precept of liberation. "Bring forth," O Cyrus, "outside" — outside the land of captivity — "the people," namely of the Jews. Jer. 5: "hear, foolish people," etc. "All the nations." Here he excludes any partnership in godhead. And first he shows the falsity of the other gods by way of a judgment, setting forth the nations' agreement with idols: "are gathered together" — into one error. Ps. 13: "all have gone astray," etc. — seeking a sign of godhead. "Who among you" — that is, which of your gods? Or he speaks to the idols, and seeks testimony. "Let them give witnesses," and "let them be justified" — that is, let them be justly called gods; and let the witnesses hear future things from them, and speak testimony on your behalf. Above, 41: "there is none announcing nor foretelling," etc. Second, he shows the truth of his own godhead: and first as to knowledge; second as to power, "you are witnesses," etc. Concerning the first, two things. First he gives testimony, assigning men as witnesses: "truly you are witnesses," etc.; "my servant" — the people of Jacob, or Christ. Acts 1: "you shall be witnesses to me," etc.; setting forth the manner of knowing: "that you may know" — as to those things which can be known of God through natural reason; and "that you may believe" — as to those things which are above reason; and thus "you may understand": for unless you shall have believed, you shall not understand, above, 8, according to another text. He also sets forth the saying of the witnesses, that he alone is God: "for I alone" — "I am" — "God." "The one who forms," or "the one formed" — namely, an idol — Deut. 32: "see that I am he alone," etc.; and that he alone is Lord: "I am" — singularly; "I am" — excellently, etc.; Acts 4: "there is no salvation in any other," etc. Second he gives a sign of godhead. "I have announced," etc.; "there was not" one from whom you could know. Ps. 80: "Israel, if you will hear me," etc. "You are witnesses," etc. Here he shows the truth of his godhead as to power: and first he gives testimony, "you are witnesses," etc., John 8: "I am the beginning," etc. Second he gives a sign of power in punishing: "and there is none who" out of the "hand" — as Deut. 32, Job 10; and in working, "I will work," etc., above, 14: "the Lord of hosts has decreed," etc. "Thus says the Lord," etc. Here he sets forth the sign of love: because for their sake he destroyed the Babylonians glorying in their ships, on account of the multitude of waters. "I have sent forth" — namely, wrath — Jer. 51: "the Lord has planned and has done," etc. "Thus says the Lord who gave," etc. Here he recalls past benefits, to confirm hope concerning future ones. And concerning this he does two things. First he recalls the past benefits when they went out from Egypt, in their governance. "In the sea" — the Red Sea, Exod. 14; "in the waters of the torrent" — in the Arnon, Numbers 21; in the Jordan, Joshua 3. And as to the destruction of enemies: "who brought forth the chariot" — the chariots of Pharaoh, etc., Exod. 15: "his chosen princes," etc.; "as flax" — cut off in a moment. Second he promises things much greater in the future; and concerning this he does three things. First he shows the greatness of future benefits by comparison with the former: "do not remember" — as if to say: they are not worthy to be held in memory in comparison with the future ones, Phil. 3: "forgetting indeed those things which are behind," etc.; by their newness: "behold I make new things" — unheard of, Apoc. 21: "behold I make all things new." And by their determination: "I will set in the desert" — that is, in the land of the Jews, which was formerly desert — "a way" — of those going to the festivities; "rivers" — of consolation, Ps. 106: "he turned the desert into pools," etc. And if these things are expounded literally of the liberation from the captivity of Babylon, they are said to be greater than the liberation from Egypt — not on account of greater miracles, but because the kings from whose power he liberated them were more powerful than Pharaoh; or because they came from a more distant place. But if they are referred to the liberation wrought through Christ, it is clear that nothing so admirable had preceded it in past ages. Second he shows the usefulness of the benefits among the nations: "and the beast of the field will glorify" — that is, the Gentile living beastially, converted to Christ; or those seeing how I free the Jews. Ps. 148: "beasts and all cattle," etc.; and among the Jews: "that I might give drink" — of doctrine and consolation, Deut. 7: "the Lord has chosen you," etc. Third he assigns the reason: "this people for myself" — unto my praise. Prov. 16: "all things for himself," etc. "You did not call upon me." Here he excludes the merits of the Jews for obtaining such great benefits; and concerning this, three things. First he excludes merit; second he gives room for a response, "bring me back to mind," etc.; third he removes a certain manner of responding, "your father," etc. Concerning the first, three things. First he excludes merit: "you did not call upon me" — and all these things are said because they did not offer these things to God with their whole heart, but partly to God, partly to idols; or because they conferred nothing on God; or because they did them in hope of temporal recompense; or because after the coming of Christ they were not accepted. Mal. 3: "who is there among you that would shut the doors," etc.; Ps. 49: "shall I eat," etc. Second he shows their guilt: "nevertheless, to serve" — as if to say: you have shown me servile, while, though you offended me, I did not punish. Above, 1: "they have become troublesome to me," etc. He speaks in a human manner. Third he shows the benefit given freely: "I am," etc., Ps. 24: "for your name's sake you will be propitious," etc., Ez. 36: "not for your sakes will I do this," etc. "Bring me to remembrance," etc. Here he gives room for a response. "Bring back" — as if to say: think again on what I have done for you; tell if you have anything, to excuse yourself, or to accuse me, that you may be justified, that is, that you may be judged just. Job 33: "if you have anything to say," etc. "Your father." Here he removes a certain way of responding. For they could allege the innocence of their fathers; but against this he speaks. "Father" — Adam, Gen. 3; Abraham, seeking a sign concerning God's promise, as though doubting, Gen. 15; "interpreters" — Moses and Aaron at the waters of contradiction, Num. 21; "I have profaned" — that is, I have allowed to be profaned — unto utter destruction: for all died in the desert, except Caleb and Joshua. Ps. 105: "we have sinned with our fathers," etc. (Collationes, chap. 43). The Lord frees the saints from fire: of carnal temptation, Job 31: "it is a fire even unto consumption," etc.; of temporal tribulation, Ps.: "you have tried me by fire"; of eternal damnation, Matt. 25: "depart, you cursed"; of divine indignation, Deut. 32: "a fire is kindled," etc. In which are burned: the lascivious, 1 Cor. 7: "it is better to marry," etc.; the impatient, above, 13: "their faces shall be burnt," etc.; the impenitent, Ps.: "the flame has burned up sinners"; the proud, the same: "the foundations of the mountains," etc. He also frees from waters: of pleasure, Prov. 9: "stolen waters," etc., in which they are suffocated through luxury; of cupidity, Exod. 15: "they sank as lead," etc., in which through avarice; of adversity, Ps.: "the waters have come in even unto the soul," etc., in which through impatience; of worldly power, Apoc. 17: "the waters upon which she sits," etc., in which through pride. Bring God back into memory as to: the wonders which he has done, that they be venerated, Ps.: "remember his wonders," etc.; the benefits which he gave, that thanks be rendered, Ecclus., last chapter: "I have remembered mercy," etc.; the torments which he endured, that compassion be shown, Lam. 3: "remember my poverty," etc.; the precepts which he gave, that they be observed, Ps.: "that they may be mindful," etc.”

“Put me in remembrance,.... Of this gracious promise of free remission of sins, and of all others of the same kind; not that God ever forgets any of his promises, but he may sometimes seem to do so; wherefore he would have his people put him in mind of them, that he may by his good Spirit make a comfortable application of them to him: "let us plead together"; or come together in judgment, as God and the sinner may upon the foot of remission of sin, through the blood, sacrifice, and satisfaction of Christ; which may be pleaded, and will be allowed, in the court of justice: declare thou, that thou mayest be justified; declare the promise before made; declare the grace that is expressed in it; plead the blood and righteousness of my Son, that thou mayest be justified by it, on which account remission of sin is: or it may be rather, these words are directed to another set of men among the Jews, who rejected the doctrine of forgiveness of sin by the grace of God, through the blood of Christ; such as were the Scribes and Pharisees in Christ's time, those self-justiciaries, who sought to be justified by the works of the law; setting at nought the grace of God and righteousness of Christ: now these the Lord calls upon in a way of derision, to put him in mind of any of their good actions they had done, and he had forgotten, for the sake of which they expected pardon, and not for his name's sake; and to come into open court and plead their own righteousness, and see whether they could carry their cause upon the foot of their own merits; and declare publicly what these merits and good works were, that they might be justified by them, if they were sufficient for such a purpose; but alas! these would not bear examination at the bar of strict justice, and would be far from justifying them in, the sight of God; and as their own works would be insufficient, it would be a vain thing to have recourse to the works and merits of their forefathers; for it follows, Put me in remembrance,.... Of this gracious promise of free remission of sins, and of all others of the same kind; not that God ever forgets any of his promises, but he may sometimes seem to do so; wherefore he would have his people put him in mind of them, that he may by his good Spirit make a comfortable application of them to him: "let us plead together"; or come together in judgment, as God and the sinner may upon the foot of remission of sin, through the blood, sacrifice, and satisfaction of Christ; which may be pleaded, and will be allowed, in the court of justice: declare thou, that thou mayest be justified; declare the promise before made; declare the grace that is expressed in it; plead the blood and righteousness of my Son, that thou mayest be justified by it, on which account remission of sin is: or it may be rather, these words are directed to another set of men among the Jews, who rejected the doctrine of forgiveness of sin by the grace of God, through the blood of Christ; such as were the Scribes and Pharisees in Christ's time, those self-justiciaries, who sought to be justified by the works of the law; setting at nought the grace of God and righteousness of Christ: now these the Lord calls upon in a way of derision, to put him in mind of any of their good actions they had done, and he had forgotten, for the sake of which they expected pardon, and not for his name's sake; and to come into open court and plead their own righteousness, and see whether they could carry their cause upon the foot of their own merits; and declare publicly what these merits and good works were, that they might be justified by them, if they were sufficient for such a purpose; but alas! these would not bear examination at the bar of strict justice, and would be far from justifying them in, the sight of God; and as their own works would be insufficient, it would be a vain thing to have recourse to the works and merits of their forefathers; for it follows, Isaiah 43:27 isa 43:27 isa 43:27 isa 43:27Thy first father hath sinned,.... Either Adam, as Kimchi, in whom all have sinned, and from whom all derive a sinful and corrupt nature; or Abraham, as Jarchi, the father of the Jewish nation, of whom they boasted, and in whom they trusted, as being of his seed, and through whose merits and worthiness they expected great things; yet he was but a sinful man, though a good man, and a great believer; of whose infirmity and frailty many instances are on record. Some have thought Terah the father of Abraham is designed, who was an idolater; others think some particular king is meant, the father of his people; Aben Ezra supposes Jeroboam to be intended, the first king of the ten tribes who made Israel to sin; but Kimchi observes, it is better to understand it of Saul, who was the first king over all Israel; others interpret it of Ahaz; and others of Manasseh; Vitringa of Uriah the priest, in the times of Ahaz; but it seems best to take the singular for the plural, as the Arabic version does, which renders it, "your first fathers have sinned"; all their forefathers had sinned, from their coming out of Egypt to that day; and, therefore it was in vain to have respect to them, or plead any worthiness of theirs in their favour; besides, they imitated them in their sins, and were filling up the measure of their iniquities: and thy teachers have transgressed against me; or "interpreters" (s); of the law to the people, the Priests and Levites, Scribes and Pharisees; such who should have taught the people, and instructed them in the knowledge of divine things, and interceded with God for them; these were transgressors of the law themselves, as well as despisers of the Gospel; these rejected the counsel of God against themselves, disbelieved the Messiah, and dissuaded the people from receiving him; they were "orators" (t), as the word is by some rendered; and they used all the oratory they were masters of against Christ, and to persuade the people into an ill opinion of him, and at last to insist upon his crucifixion. (s) "interpretes tui", V. L. Pagninus, Montanus, Vatablus. (t) "Oratores", Cocceius; "interpretes, seu oratores tui", Piscator; "oratores, intercessores tui", Vitringa.”

“I, even I--the God against whom your sin is committed, and who alone can and will pardon. (Isa 44:22). for mine own sake-- (Isa 48:9, Isa 48:11). How abominable a thing sin is, since it is against such a God of grace! "Blotted out" is an image from an account-book, in which, when a debt is paid, the charge is cancelled or blotted out. not remember . . . sins-- (Jer 31:34). When God forgives, He forgets; that is, treats the sinner as if He had forgotten his sins.”

“Nevertheless, the sustaining power of divine love is greater than the gravitating force of divine wrath. "I, I alone, blot out thy transgressions for my own sake, and do not remember thy sins." Jehovah Himself here announces the sola gratia and sola fides. We have adopted the rendering "I alone," because the threefold repetition of the subject, "I, I, He is blotting out thy transgressions," is intended to affirm that this blotting out of sin is so far from being in any way merited by Israel, that it is a sovereign act of His absolute freedom; and the expression "for my own sake," that it has its foundation only in God, namely, in His absolute free grace, that movement of His love by which wrath is subdued. For the debt stands written in God's own book. Justice has entered it, and love alone blots it out (mâchâh, ἐξαλείφει, as in Isa 44:22; Psa 51:3, Psa 51:11; Psa 109:14); but, as we know from the actual fulfilment, not without paying with blood, and giving the quittance with blood.”
