Êxodo 18:22

22 Have them serve as judges for the people at all times, but have them bring every difficult case to you; the simple cases they can decide themselves. That will make your load lighter, because they will share it with you.

22 and let them judge the people at all seasons: and it shall be, that every great matter they shall bring unto thee, but every small matter they shall judge themselves: so shall it be easier for thyself, and they shall bear [the burden] with thee.
