because a will is in force only when somebody has died; it never takes effect while the one who made it is living.
For a will takes effect only at death, since it is not in force as long as the one who made it is alive.
For a covenant is valid only when men are dead, for it is never in force while the one who made it lives.
The will goes into effect only after the person’s death. While the person who made it is still alive, the will cannot be put into effect.
For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
For a testament is in force after men are dead, since it has no power at all while the testator lives.
For a testament [is] of force when men are dead, since it is in no way of force while the testator is alive.)
