John Wesley on Hebrews 9:15

And for this end he is the Mediator of a new covenant, that they who are called - To the engagements and benefits thereof. Might receive the eternal inheritance promised to Abraham: not by means of legal sacrifices, but of his meritorious death. For the redemption of the transgressions that were under the first covenant - That is, for the redemption of transgressors from the guilt and punishment of those sins which were committed in the time of the old covenant. The article of his death properly divides the old covenant from the new.
