Hebrews 9:17 in the King James Version
For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
Context
16 For where a last will and testament is, there must of necessity be the death of him who made it.
17 For a will is in force where there has been death, for it is never in force while he who made it lives.
18 Therefore even the first covenant has not been dedicated without blood.
