Galatians 3:16-18

16But to Abraham were the promises addressed, and to his seed: he does not say, And to seeds, as of many; but as of one, And to thy seed; which is Christ.

17Now I say this, A covenant confirmed beforehand by 1God, the law, which took place four hundred and thirty years after, does not annul, so as to make the promise of no effect.

18For if the inheritance [be] on the principle of law, [it is] no longer on the principle of promise; but 2God gave it in grace to Abraham by promise.
