Hebrews 9:17 in the World English Bible
For a will is in force where there has been death, for it is never in force while he who made it lives.
Context
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.
18 Whereupon neither the first testament was dedicated without blood.
