Hebrews 9:15-18

15Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.

16For where a will is involved, the death of the one who made it must be established.

17For a will takes effect only at death, since it is not in force as long as the one who made it is alive.

18Therefore not even the first covenant was inaugurated without blood.
