7 If the first covenant had been faultless, there would have been no need for a second covenant to replace it. 8 But when God found fault with the people, he said: "The day is coming, says the Lord, when I will make a new covenant with the people of Israel and Judah. 9 This covenant will not be like the one I made with their ancestors when I took them by the hand and led them out of the land of Egypt. They did not remain faithful to my covenant, so I turned my back on them, says the Lord . 10 But this is the new covenant I will make with the people of Israel on that day, says the Lord : I will put my laws in their minds, and I will write them on their hearts. I will be their God, and they will be my people. 11 And they will not need to teach their neighbors, nor will they need to teach their relatives, saying, 'You should know the Lord .' For everyone, from the least to the greatest, will know me already. 12 And I will forgive their wickedness, and I will never again remember their sins." 13 When God speaks of a "new" covenant, it means he has made the first one obsolete. It is now out of date and will soon disappear.

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.
