Galatians 3:15-17

151Brethren, 2I speak 3in terms of human relations: 4even though it is only a man’s 5covenant, yet when it has been ratified, no one sets it aside or adds 6conditions to it.

16Now the promises were spoken 7to Abraham and to his seed. He does not say, “And to seeds,” as referring to many, but rather to one, “8And to your seed,” that is, Christ.

17What I am saying is this: the Law, which came 9four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise.
