31:33 But this [shall be] the covenant that I will make with the house of Israel; After {k} those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
(k) In the time of Christ, my law will instead of tables of stone be written in their hearts by my Holy Spirit, He 8:10.
31:33 With - That is, with those who are Jews inwardly. And write it - The prophet's design is here to express the difference betwixt the law and the gospel. The first shews duty, the latter brings the grace of regeneration, by which the heart is changed, and enabled for duty. All under the time of the law that came to salvation, were saved by this new covenant; but this was not evidently exhibited; neither was the regenerating grace of God so common under the time of the law, as it hath been under the gospel.
31:27-34 The people of God shall become numerous and prosperous. In Heb 8:8,9, this place is quoted as the sum of the covenant of grace made with believers in Jesus Christ. Not, I will give them a new law; for Christ came not to destroy the law, but to fulfil it; but the law shall be written in their hearts by the finger of the Spirit, as formerly written in the tables of stone. The Lord will, by his grace, make his people willing people in the day of his power. All shall know the Lord; all shall be welcome to the knowledge of God, and shall have the means of that knowledge. There shall be an outpouring of the Holy Spirit, at the time the gospel is published. No man shall finally perish, but for his own sins; none, who is willing to accept of Christ's salvation.
