16 Now the promises were spoken to Abraham and to his offspring; he does not say: And to offsprings, as if he spoke of many; but as of one, And to your offspring, which is Christ.
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.
