Oecumenius

"Sacrifice and offering you did not desire." Those prescribed by the law, evidently. But offering here signifies something different from sacrifice; and I think the bloodless ones are indicated by the name. From here the person of Christ is introduced, saying to the Father, Since, He says, O Father, “Sacrifice and offering and burnt offerings and sacrifices for sin you did not desire nor did you take pleasure in," which are offered according to the law."
"for sin." That is, an offering concerning sin. Commonly, you have taken pleasure. And he rightly says, "for sin." For of the sacrifices, some were offered for salvation, and others for sin; as if he said, "Since in no way did you will any offering or sacrifice, nor burnt offerings, neither concerning salvation, nor concerning sin, I have come, having taken a body, to become a pleasing sacrifice to you, which I myself have prepared."
For the Holy Spirit and the power of the Most High overshadowed the Virgin. (Luke 1:35) And it was said, that I may do your will, O Father (Jn. 6:38); that those whom you have given me, I may not lose any of them. (Jn. 18:9) The title of the book, the Hebrews say, is the Law. Isaiah, teaching about the mystery of the Incarnation of the Only Begotten, heard; "Write for me in it with a man's pen." (Isa. 8:1) That it is a sacrifice and offering. Do you see that the sacrifices were cast aside even before the incarnation?
For after not wanting, he says, Burnt offerings and sacrifices, Then I said, "Behold, I have come. Who said, Behold, I come? Christ, obviously. I have come to do your will. But what is the will of the Father, but that the Son be crucified? And that I have come, he says, and I will do your will, it is written in the scroll of the book, he says, about me these things. Thus it is necessary to arrange. For being prophetic, it is a difficulty. The scroll of the book is the bundle of the law, that is, the book of the Old Testament. Therefore, in this Scripture it is written concerning my coming and that I am to be offered for the world.
"you did not desire nor did you take pleasure in."Paul himself interprets the Davidic more clearly.
"which are offered according to the law," that is, the Jewish law, and they are offered by the Jews. Do you see that before the descent, the sacrifices were hated?
"to do your will, O God." What then? Were the sacrifices according to the law not the will of God? They were, but necessarily. For he did not say to them only this, that in general the sacrifices of animals are detestable to me, the incorporeal one. But since you desire to offer sacrifices, at least offer them to me and not to the idols, which was not of a pure and original will.
"the first in order to establish the second.” What is the first? The sacrifices. What is the second? The cross. Therefore, the sacrifices are expelled, and the cross, that is, the sacrifice of Christ, is introduced.
“we have been sanctified.” By which will, he says, you are sanctified. Of which? Of the cross, through the offering of the body of Jesus Christ. For we have not only obtained forgiveness, but we have also been sanctified.
"the offering of the body of Jesus Christ." Behold, he has interpreted what the will of the Father is; the offering of the body of Christ. For since he was speaking above and below about the will, he then said what the will is.
"Once," he says, that is, not in the manner of the Jewish sacrifices, but once. "Once, indeed." The offering of the body of Jesus Christonce for all.That is, those who are sanctified through the once-for-all offering of the body of Jesus Christ.

when coming into the world, Christ said, but coming into. He was coming into, namely, when he promised to David, and he was extending, from the fruit of his womb, to sit him upon his throne forever. (Ps. 131:11) Therefore, entering the world through the covenants with David, and this he says through him, that "Since you did not desire sacrifice and offering," (Ps. 39:7) nor were you pleased with the things done in the law. And he did not say, "You do not take pleasure nor desire," but, "you did not desire, you did not take pleasure in," only saying, as if from the very foundation of them and the beginning of those things, that the whole sacrifices were not acceptable and pleasing to you. But even if something of theirs has been accepted by you, it has been accepted due to the weakness of those presenting it. Therefore, when I have also dismissed these things and have prepared a body for myself, then I come to do your will. For this has been said about me not simply and in passing, but as the main point and premise of the book concerning my proclamation. And the book speaks of the whole old one. For the chief point and the most esteemed hypothesis of the old covenant is the prophecies concerning Christ.

"But He, having offered one sacrifice," Christ evidently.
"for sins." For our sins, for which he suffered.
"for all time." Christ, clearly, offered one sacrifice, namely, His own body, for our sins, sufficient for us forever, so that there would be no need for a second.
"sat down at the right hand of God."He is not only a high priest, but also God. After completing the work, through which He also became a high priest and stewarded the administration, He sat down as God and awaits.
"from that time onward." And for what reason were his enemies not immediately placed under his feet? For the sake of those who are to become and give birth to believers. For not only demons are enemies, but also unbelievers.But now Paul especially calls the unbelieving Hebrews enemies, comforting the faithful from the Jews who have suffered countless terrible things at their hands.
"until His enemies be made." He did not say "they will be subjected," but signifying the greatest of subjection, he said "they be made," a footstool for his feet. For their being made as a footstool is a proof of his sitting at the right hand of the Father.
"For by one offering," which Christ offered, he perfected, having made perfect, he completely freed from sins.
"those who are being sanctified."That is, the faithful. For they are sanctified by the aforementioned offering.
"And the Holy Spirit also testifies to us." What does it bear witness to? That our sins have been forgiven.
"And their sins." He added, he says, "And their sins I will remember no more." Do you see that he testified to the forgiveness of sins? Then he forgave when he established the new covenant. And the new covenant was given through the sacrifice of his Son Jesus Christ our Lord.
"Now where there is forgiveness of these things." Of sins, obviously.
"there is no longer an offering for sin." For who, he says, has need of many offerings, when the one that Christ presented is sufficient to take away sins?

Since he demonstrated the superiority of our high priest over the former ones, and the superiority of the new covenant over the old one, and the superiority of Christ's offering over the legal sacrifices; and that through it we have been freed from sins, he indeed refreshes the doctrinal discourse, giving the listener a breathing space; but he also very aptly moves on to the discourse concerning life. Pay close attention: for having been reminded of the forgiveness of sins, he subsequently exhorts us not to fall into the same sins again.
"Boldness to enter." Just as, he says, we were previously ashamed, full of sins, so now we have boldness to enter into heaven, because of the forgiveness granted to us.
"to enter the holy places." He speaks of heaven and the progress into the spiritual. By the blood of Jesus. "by the blood." For by the blood of the cross of Christ, we have forgiveness and boldness.
"which He inaugurated for us." It was the entrance of the holy places, and a path leading to it, recently cut. For this, it is said, was inaugurated.
"new." Which in our times, he says, took its beginning. And this is our claim, that in the times around Abraham, this road did not exist, but was established among us.
"and living." For the first way led to death and to disbelief; this one, however, truly brings to life, since it itself lives and endures.

"let us draw near with a true heart." In the faith of Christ with truth, having nothing false or deceitful.
"in full assurance of faith." For hereafter, nothing is visible, neither the temple, that is, the heaven, nor the high priest, that is, Christ, nor the sacrifice, that is, his body, but there is a need for faith. And since there is both believing and doubting, he says, "in full assurance of faith," that is, so that we may be fully informed about these things.
"having our hearts sprinkled." This shows that there is a need not only for faith but also for a righteous life.
"sprinkled." The Jews, he says, sprinkle their bodies; but let us sprinkle and purify our consciences, so that we may not have any evil consciousness of ourselves.
"with pure water," that is, with baptism. For the Jews, by washing, only cleanse the body; but we purify the soul with baptism. For the water we have is pure, that is, purifying.
"let us hold fast the confession."Let us hold fast, he says, the confession of our hope, firm and without wavering. What hope? To hope through the blood of Christ for entrance into heaven. To have our sins forgiven through Him. To be made worthy of adoption through Him.
"For faithful," that is, "true is He who promised." And what did He promise? That we would enter into His kingdom; "for I will," He says, "that where I am, there these may be also." (Jn. 16:24) For "these" He spoke of the faithful.

"after we have received the knowledge." That is, the faith concerning Christ.
"there no longer remains a sacrifice for sins." In order to erase sins. For among the Jews there were victims that were offered for their remission, so that they were not for involuntary sins.
"remains a sacrifice." It does not abolish repentance, may it not be; but it prohibits the existence of a second baptism. For here, it calls the cross and baptism a sacrifice, just as it says elsewhere. "For by one offering He has perfected for all time those who are sanctified." (Heb. 10:14)
"and fiery anger." Just as that fiery, being pierced by some anger, consumes and devours those who are struck. He speaks of opposers, not only of the unbelievers, but also of those who act directly against the commandments of Christ.
"Anyone who has rejected Moses' law." A comparison is made from the lesser. For he wishes to show the destruction by fire justly inflicted against the adversaries. However, he speaks of the law to Moses (Lev. 4:26), because he commanded many things that are contained in the law.
"on the testimony of two or three witnesses."If two or three had testified, there was no longer a place for mercy or pardon, but he would die. Therefore, if someone who has transgressed the law of man, that is, of Moses, dies without pardon after a strong testimony, he says, what should happen to those who have trampled the law of Christ?
“who has trampled the Son of God."How does one trample on the Son of God? When he does not listen to Him, when he who shares in Him commits sins: for that is to trample, namely to despise.
"in the blood of the covenant." He refers to the blood of Christ: for through it we have received the new covenant.
"and having shared." Having shared, as having nothing more excellent than the others, just as those who say that he is a naked man. For they say that he is nothing but blood, in which he differs from ours as far as honor is concerned. Then, showing their ingratitude, he says: by which he was sanctified.
"and insulted the Spirit of grace? " For he who has not received the benefit of the gift insulted the one who gave it. He made you a son of God, but you prefer to become a servant. He came to dwell in you, yet you introduce the Devil within yourself. Are these not injuries and insults against the Spirit?
"For we know Him who said." And that these things are true, God himself testifies who says: "Vengeance is mine." This is with me, to take vengeance: "I will repay, says the Lord." But by saying this, he comforts them about the evils they have suffered from their own fellow citizens. As if he were saying: He said this gently, and he comforts them regarding the evils they suffered from their own fellow citizens, as if he were saying: "Why are you anxious? You have the one who avenges and gives back justice to those who serve you."
