Galatians 3:18-20

King James Version

¹⁸ For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.

¹⁹ Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.

²⁰ Now a mediator is not a mediator of one, but God is one.
