Galatians 3:18

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

17 What 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.

For 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.

19 Why then was the law given? It was added because of transgressions, until the arrival of the seed to whom the promise referred. It was administered through angels by a mediator.

20 A mediator is unnecessary, however, for only one party; but God is one.

Do read the surrounding verses too, because the context often says more than a single verse.
