For a will takes effect only at death, since it is not in force as long as the one who made it is alive.
Then Israel said to Joseph, “Behold, I am about to die, but God will be with you, and will bring you again to the land of your fathers.
Peace I leave with you; my peace I give to you; not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
To give a human example, brethren: no one annuls even a man's will, or adds to it, once it has been ratified.
For where a will is involved, the death of the one who made it must be established.
Hence even the first covenant was not ratified without blood.
