Brethren, I speak according to the practice of men; contracts between men, when once ratified, cannot be disannulled or altered afterwards by any man.

this therefore I say, that the law, which was not till four hundred and thirty years after, cannot disannul the promise, that was ratified before by God, so as to set the promise afoot.
