Hebrews 10:15

“Wherefore the Holy Ghost also is a witness to us, etc..] In (<243133>Jeremiah 31:33,34). This preface to the following citation shows that the books of the Old Testament are of divine original and authority; that the penmen of them were inspired by the Holy Ghost; that he existed in the times of the Old Testament; that he is truly and properly God, the Lord, or Jehovah, that speaks in the following verses; and that he is a distinct divine Person, and the author of the covenant of grace; and in what he says in that covenant, he bears testimony to the truths before delivered, concerning the insufficiency and abolition of legal sacrifices, and of full and perfect remission of sin, by the blood…”

“The Greek, has "moreover," or "now." is a witness--of the truth which I am setting forth. The Father's witness is given Heb 5:10. The Son's, Heb 10:5. Now is added that of the Holy Spirit, called accordingly "the Spirit of grace," Heb 10:29. The testimony of all Three leads to the same conclusion (Heb 10:18). for after that he had said before--The conclusion to the sentence is in Heb 10:17, "After He had said before, This is the covenant that I will make with them (with the house of Israel, Heb 8:10; here extended to the spiritual Israel) . . . saith the Lord; I will put (literally, 'giving,' referring to the giving of the law; not now as then, giving into the hands, but giving) My laws into…”

“Whereof the Holy Ghost is a witness to us - That is, the Holy Spirit is a proof of the truth of the position here laid down - that the one atonement made by the Redeemer lays the foundation for the eternal perfection of all who are sanctified. The witness of the Holy Spirit here referred to is what is furnished in the Scriptures, and not any witness in ourselves. Paul immediately makes his appeal to a passage of the Old Testament, and he thus shows his firm conviction that the Scriptures were inspired by the Holy Spirit. For after that he had said before - The apostle here appeals to a passage which he had before quoted from Jeremiah 31:33-34; see it explained in the notes on Hebrews 8:8-12.…”

“In Heb 10:15-18, the apostle winds up his argument concerning the excellency and perfection of the priesthood and sacrifice of Christ. He had proved this before by a quotation from Jeremiah; which he here repeats, describing the new covenant as now completely ratified, and all the blessings of it secured to us by the one offering of Christ, which renders all other expiatory sacrifices, and any repetition of his own, utterly needless. Hebrews 10:16”

“10:15-17 The author again quotes from Jer 31:33-34 (see Heb 8:7-12) to support the statement in 10:14, that Christ’s one offering under the new covenant has made worshipers perfect forever. • God’s laws have now been placed in their hearts and on their minds. This has internalized the believer’s relationship with God. • I will never again remember their sins and lawless deeds: As the author has shown (9:11–10:14), the superior sacrifice of Christ has made this new covenant reality possible.”
