Hebrews 9:17

For a will takes effect only at death, since it is not in force as long as the one who made it is alive.

To give a human example, brothers:even with a man-made covenant, no one annuls it or adds to it once it has been ratified.

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.
