For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.

For then they would have ceased to be offered: because the worshippers once cleansed should have no conscience of sin any longer:

Since, would they not indeed have ceased being offered, on account of the worshippers once purged having no longer any conscience of sins?

Else would they not have ceased to be offered, because the worshippers, having been once cleansed, would have had no more conscience of sins?

For then would they not have ceased to be offered? because that the worshipers once cleansed, would have had no more conscience of sins.

since, would they not have ceased to be offered, because of those serving having no more conscience of sins, having once been purified?

For then would not the sacrifices have ceased to be offered, because the consciences of the worshippers - who in that case would now have been cleansed once for all - would no longer be burdened with sins?

For if this had been possible, would there not have been an end of those offerings, because the worshippers would have been made completely clean and would have been no longer conscious of sins?

Otherwise, they would have ceased to be offered, because the worshipers, once cleansed, would no longer be conscious of any sin.

Otherwise, would not the offering of these sacrifices have been abandoned, as the worshipers, having been once purified, would have had their consciences clear from sins?

Alioqui annon desiisent offeri? propterea quod nullam amplius conscientiam peccatorum haberent cultores semel purgati.

For then would they not have ceased to be offered? - Margin, "Or they would have." The sense is the same. The idea is, that the very fact that they were repeated showed that there was some deficiency in them as to the matter of cleansing the soul from sin. If they had answered all the purposes of a sacrifice in putting away guilt, there would have been no need of repeating them in this manner. They were in this respect like medicine. If what is given to a patient heals him, there is no need of repeating it; but if it is repeated often it shows that there was some deficiency in it, and if taken periodically through a man's life, and the disease should still remain, it would show that it was not sufficient to effect his cure. So it was with the offerings made by the Jews. They were offered every year, and indeed every day, and still the disease of sin remained. The conscience was not satisfied; and the guilty felt that it was necessary that the sacrifice should be repeated again and again.
Because that the worshippers once purged should have had no more conscience of sin - That is, if their sacrifices had so availed as to remove their past sins, and to procure forgiveness, they would have had no more trouble of conscience on account of them. They would not have felt that it was necessary to make these sacrifices over and over again in order to find peace. When a man has full evidence that an atonement has been made which will meet all the demands of the Law, and which secures the remission of sin, he feels that it is enough. It is all that the case demands, and his conscience may have peace. But when he does "not" feel this, or has not evidence that his sins are all forgiven, those sins will rise to remembrance, and he will be alarmed. He may be punished for them after all. Thence it follows that if a man wants peace he should have good evidence that his sins are forgiven through the blood of the atonement.
No temporary expedient; no attempt to cover them up; no effort to forget them will answer the purpose. They "must be blotted out" if he will have peace - and that can be only through a perfect sacrifice. By the use of the word rendered "conscience" here, it is not meant that he who was pardoned would have no "consciousness" that he was a sinner, or that he would forget it, but that he would have no trouble of conscience; he would have no apprehension of future wrath. The pardon of sin does not cause it to cease to be remembered. He who is forgiven may have a deeper conviction of its evil than he had ever had before. But he will not be troubled or distressed by it as if it were to expose him to the wrath of God. The remembrance of it will humble him; it will serve to exalt his conceptions of the mercy of God and the glory of the atonement, but it will no longer overwhelm the mind with the dread of hell. This effect, the apostle says, was not produced on the minds of those who offered sacrifices every year. The very fact that they did it, showed that the conscience was not at peace.

Would they not have ceased to be offered? - Had they made an effectual reconciliation for the sins of the world, and contained in their once offering a plenitude of permanent merit, they would have ceased to be offered, at least in reference to any individual who had once offered them; because, in such a case, his conscience would be satisfied that its guilt had been taken away. But no Jew pretended to believe that even the annual atonement cancelled his sin before God; yet he continued to make his offerings, the law of God having so enjoined, because these sacrifices pointed out that which was to come. They were offered, therefore, not in consideration of their own efficacy, but as referring to Christ; See on Hebrews 9:9 (note).

For then would they not have ceased to be offered,.... The Complutensian edition, and the Syriac and Vulgate Latin versions, leave out the word "not"; and the sense requires it should be omitted, for the meaning is, that if perfection had been by the legal sacrifices, they would have ceased to have been offered; for if the former ones had made perfect, there would have been no need of others, or of the repetition of the same; but because they did not make perfect, therefore they were yearly renewed; unless the words are read with an interrogation, as they are in the Arabic version, "for then would they not have ceased to be offered?" yes, they would; they are indeed ceased now, but this is owing to Christ and his sacrifice, and not to the efficacy of these sacrifices; for yearly sacrifices were offered for former sins, as well as for fresh ones, as appears from the following verse.
Because the worshippers, once purged, would have had no more conscience of sins; there are external and internal worshippers; the latter are such who worship God in Spirit and in truth: but here ceremonial worshippers are meant, who, if they had been really purged from sin by legal sacrifices, and purifications, would have had no more conscience of sins, and so have had no need to have repeated them; as such spiritual worshippers, who are once purged from sin by the blood and sacrifice of Christ; not that they have no sin, or no sense of sin, or that their consciences are seared, or that they never accuse for sin, or that they are to make no confession and acknowledgment of sin; but that they are discharged from the guilt of sin, and are not liable to condemnation for it; and through the application of the blood of Christ to them, have peace with God, and joy in the Holy Ghost.

For--if the law could, by its sacrifices, have perfected the worshippers.
they--the sacrifices.
once purged--IF they were once for all cleansed (Hebrews 7:27).
conscience--"consciousness of sin" (Hebrews 9:9).

They who had been once perfectly purged, would have been no longer conscious either of the guilt or power of their sins.
