Hebrews 9:15-17 King James Version (KJV)
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
16 For where a testament is, there must also of necessity be the death of the testator.
17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
Hebrews 9:15-17 New International Version (NIV)
15 For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant.
16 In the case of a will,[a] it is necessary to prove the death of the one who made it, 17 because a will is in force only when somebody has died; it never takes effect while the one who made it is living.
