-- Is 42:1-7
The perfect fulfillment of the Law could be the work of none but the divine legislator, born subject to the Law in the person of the Son. In Jesus, the Law no longer appears engraved on tables of stone but "upon the heart" of the Servant who becomes "a covenant to the people", because he will "faithfully bring forth justice". Jesus fulfills the Law to the point of taking upon himself "the curse of the Law" incurred by those who do not "abide by the things written in the book of the Law, and do them", for his death took place to redeem them "from the transgressions under the first covenant".
