Hebrews 9:15-18

15For this reason He is the mediator of a new covenant, in order that those called may receive the promised eternal inheritance—since a death has taken place that redeems them from violations under the first covenant.

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

17For a covenant is secured upon the basis of dead bodies, since it has no strength as long as the one who made it lives.

18That is why not even the first covenant was inaugurated without blood.
