Galatians 3:15-17 Christian Standard Bible (CSB)
15 Brothers and sisters, I’m using a human illustration. No one sets aside or makes additions to a validated human will.[a] 16 Now the promises were spoken to Abraham and to his seed. He does not say “and to seeds,” as though referring to many, but referring to one, and to your seed,[b] who is Christ. 17 My point is this: The law, which came 430 years later, does not invalidate a covenant previously established by God[c] and thus cancel the promise.
