To give a human example, brethren: even though it is only a man's covenant, yet when it has been ratified, no one sets it aside or adds conditions to it.

John 14:27

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.
