19 Wherefore then, the law was added because of transgressions, till the seed should come to whom the promise was made in the law given to Moses, who was ordained by the hand of angels to be a mediator of this first covenant, (the law.)

20 Now this mediator was not a mediator of the new covenant; but there is one mediator of the new covenant, who is Christ, as it is written in the law concerning the promises made to Abraham and his seed. Now Christ is the mediator of life; for this is the promise which God made unto Abraham.
