8 For finding fault, He saith to them, 'Lo, days come, saith the Lord, and I will complete with the house of Israel, and with the house of Judah, a new covenant, 9 not according to the covenant that I made with their fathers, in the day of My taking 'them' by their hand, to bring them out of the land of Egypt—because they did not remain in My covenant, and I did not regard them, saith the Lord,— 10 because this 'is' the covenant that I will make with the house of Israel, after those days, saith the Lord, giving My laws into their mind, and upon their hearts I will write them, and I will be to them for a God, and they shall be to Me for a people; 11 and they shall not teach each his neighbour, and each his brother, saying, Know thou the Lord, because they shall all know Me from the small one of them unto the great one of them, 12 because I will be merciful to their unrighteousness, and their sins and their lawlessnesses I will remember no more;'— 13 in the saying 'new,' He hath made the first old, and what doth become obsolete and is old 'is' nigh disappearing.

Commentary on Hebrews 8:7-13
(Read Hebrews 8:7-13)
The superior excellence of the priesthood of Christ, above that of Aaron, is shown from that covenant of grace, of which Christ was Mediator. The law not only made all subject to it, liable to be condemned for the guilt of sin, but also was unable to remove that guilt, and clear the conscience from the sense and terror of it. Whereas, by the blood of Christ, a full remission of sins was provided, so that God would remember them no more. God once wrote his laws to his people, now he will write his laws in them; he will give them understanding to know and to believe his laws; he will give them memories to retain them; he will give them hearts to love them, courage to profess them, and power to put them in practice. This is the foundation of the covenant; and when this is laid, duty will be done wisely, sincerely, readily, easily, resolutely, constantly, and with comfort. A plentiful outpouring of the Spirit of God will make the ministration of the gospel so effectual, that there shall be a mighty increase and spreading of Christian knowledge in persons of all sorts. Oh that this promise might be fulfilled in our days, that the hand of God may be with his ministers so that great numbers may believe, and be turned to the Lord! The pardon of sin will always be found to accompany the true knowledge of God. Notice the freeness of this pardon; its fulness; its fixedness. This pardoning mercy is connected with all other spiritual mercies: unpardoned sin hinders mercy, and pulls down judgments; but the pardon of sin prevents judgment, and opens a wide door to all spiritual blessings. Let us search whether we are taught by the Holy Spirit to know Christ, so as uprightly to love, fear, trust, and obey him. All worldly vanities, outward privileges, or mere notions of religion, will soon vanish away, and leave those who trust in them miserable for ever.
