Galatians 3:17-24 And this I affirm, that the covenant which had been before confirmed by God with respect to Christ, the law, which was four hundred and thirty years after, could not annul so as to make the promise of no effect.

Anderson⁽ⁱ⁾ ¹⁷ And this I affirm, that the covenant which had been before confirmed by God with respect to Christ, the law, which was four hundred and thirty years after, could not annul so as to make the promise of no effect. ¹⁸ For if the inheritance be by law, it is no longer by promise: but God bestowed it on Abraham by promise. ¹⁹ What, then, was the purpose of the law? It was added on account of transgressions, (till the offspring should come, to whom the promise was made,) having been appointed through the service of angels, in the hand of a mediator. ²⁰ Now, a mediator for one is impossible; but God is one. ²¹ Is the law, then, against the promises of God? It can not be. For if a law had been given which could have given life, surely righteousness would have been by law. ²² But the scripture has shut up all under sin, that the promise by faith in Christ Jesus may be given to those who believe. ²³ But before the faith came, we were kept under law, being shut up to the faith which was to be revealed. ²⁴ So, then, the law was our pedagogue that led us to Christ, that we might be justified by faith.
