Galatians 3:17-19

New King James Version

¹⁷ And this I say, that the law, ^(A)which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God ^[a]in Christ, ^(B)that it should make the promise of no effect. ¹⁸ For if ^(C)the inheritance is of the law, ^(D)it is no longer of promise; but God gave it to Abraham by promise.

Purpose of the Law

¹⁹ What purpose then does the law serve? ^(E)It was added because of transgressions, till the ^(F)Seed should come to whom the promise was made; and it was ^(G)appointed through angels by the hand ^(H)of a mediator.
