Hebrews 9:11-12

Redemption Through the Blood of Christ

11But when Christ appeared as a high priest aof the good things that have come,
Some manuscripts  good things to come
then through cthe greater and more perfect tent ( dnot made with hands, that is, not of this creation)
12he eentered fonce for all into the holy places, not by means of gthe blood of goats and calves but hby means of his own blood, ithus securing an eternal redemption.

Hebrews 9:15-17

15Therefore he is jthe mediator of a new covenant, so that kthose who are called may lreceive the promised eternal inheritance, msince a death has occurred that redeems them from the transgressions committed under the first covenant.
The Greek word means both  covenant and will; also verses 16, 17
16For where a will is involved, the death of the one who made it must be established. 17For oa will takes effect only at death, since it is not in force as long as the one who made it is alive.
