Galatians 3:16-17

16Now athe promises were made bto Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, cAnd to your offspring,” who is Christ. 17This is what I mean: the law, which came d430 years afterward, does not annul a covenant previously ratified by God, so as eto make the promise void.
