Keep This and You'll Keep Them All There is one commandment that, if followed by all of humanity, would instantly create a peaceful world: Do not steal. The Eighth Commandment implicitly prohibits murder (stealing a life), slavery (stealing a person's freedom), adultery (stealing a spouse), humiliation (stealing dignity), and so many other sins laid out in the Bible. If there is one commandment that summarizes the other nine, this one is it.
