Galatians 3:16-18

16The promises were spoken to Abraham and to his seed. The Scripture does not say, “and to seeds,” meaning many, but “and to your seed,”1 meaning One, who is Christ.

17What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise. 18For if the inheritance depends on the law, then it no longer depends on a promise; but God freely granted it to Abraham through a promise.
