Hebrews 9:15-17

Worsley(i) 15 And on this account He is the mediator of a new covenant, that undergoing death for the redemption of transgressions against the first covenant, they that are called might receive the promise of an eternal inheritance. 16 For where a testament is, there is a necessity of proving the death of the testator. 17 For a testament is valid after men are dead, but is of no force while the testator is living.
