Hebrews 8:10-12

Verse 10

This is the covenant - This is the nature of that glorious system of religion which I shall publish among them after those days, i.e., in the times of the Gospel.

I will put my laws into their mind - I will influence them with the principles of law, truth, holiness, etc.; and their understandings shall he fully enlightened to comprehend them.

And write them in their hearts - All their affections, passions, and appetites, shall be purified and filled with holiness and love to God and man; so that they shall willingly obey, and feel that love is the fulfilling of the law: instead of being written on tables of stone, they shall be written on the fleshly tables of their hearts.

I will be to them a God - These are the two grand conditions by which the parties in this covenant or agreement are bound:

1. I will be your God.

2. Ye shall be my people.

As the object of religious adoration to any man is that Being from whom he expects light, direction, defense, support, and happiness: so God, promising to be their God, promises in effect to give them all these great and good things. To be God's people implies that they should give God their whole hearts, serve him with all their light and strength, and have no other object of worship or dependence but himself. Any of these conditions broken, the covenant is rendered null and void, and the other party absolved from his engagement.
Verse 11

They shall not teach every man his neighbor - Under the old covenant, properly speaking, there was no public instruction; before the erection of synagogues all worship was confined at first to the tabernacle, afterwards to the temple. When synagogues were established they were used principally for the bare reading of the law and the prophets; and scarcely any such thing as a public ministry for the continual instruction of the common people was found in the land till the time of John the Baptist, our Lord, and his apostles. It is true there were prophets who were a sort of general teachers, but neither was their ministry extended through all the people; and there were schools of the prophets and schools of the rabbins, but these were for the instruction of select persons. Hence it was necessary that every man should do what he could, under that dispensation, to instruct his neighbor and brother. But the prophecy here indicates that there should be, under the Gospel dispensation, a profusion of Divine light; and this we find to be the case by the plentiful diffusion of the sacred writings, and by an abundant Gospel ministry: and these blessings are not confined to temples or palaces, but are found in every corner of the land; so that, literally, all the people, from the least to the greatest, know and acknowledge the only true God, and Jesus Christ whom he has sent. Almost every man, at least in this land, has a Bible, and can read it; and there is not a family that has not the opportunity of hearing the Gospel preached, explained, and enforced.

Some have thought that from the least to the greatest is intended to signify the order in which God proceeds with a work of grace; he generally begins with the poor, and through these the great and the high often hear the Gospel of Christ.

Verse 12

I will be merciful to their unrighteousness - In order to be their God, as mentioned under the preceding verse, it is requisite that their iniquity should be pardoned; this is provided for by the immolation of Jesus Christ as the covenant sacrifice. By his blood, redemption has been purchased, and all who with penitent hearts believe on the Lord Jesus receive remission of sins, and God remembers their iniquities no more against them so as to punish them on that account. All spiritual evil against the nature and law of God is represented here under the following terms: -

1. Unrighteousness, αδικια, injustice or wrong. This is against God, his neighbor, and himself.

2. Sin, ἁμαρτια, deviation from the Divine law; Missing the Mark; aiming at happiness but never attaining it, because sought out of God, and in the breach of his laws.

3. Iniquity, ανομια, lawlessness, not having, knowing, or acknowledging, a law; having no law written in their hearts, and restrained by none in the conduct of their lives. All these are to be removed by God's mercy; and this is to be understood of his mercy in Christ Jesus.
