Galatians 3:17-19

Darby Translation

¹⁷ Now I say this, A covenant confirmed beforehand by God, the law, which took place four hundred and thirty years after, does not annul, so as to make the promise of no effect.

¹⁸ For if the inheritance [be] on the principle of law, [it is] no longer on the principle of promise; but God gave it in grace to Abraham by promise.

¹⁹ Why then the law? It was added for the sake of transgressions, until the seed came to whom the promise was made, ordained through angels in [the] hand of a mediator.
