Hebreus 9

15 And because of this he is mediator of a new covenant, so that a death having occurred for the redemption of the transgressions against the first covenant, those who are called might take the promise of the eternal inheritance.

16 For where a covenant is, a necessity is to present the death of the man who made the covenant.

17 For a covenant is effective with the dead, since it is never enforced while the man who made the covenant lives.
