Exodus 18:19-22

19Listen now to me and I will give you some advice, and may God be with you. You must be the people’s representative before God and bring their disputes to him. 20Teach them his decrees and instructions, and show them the way they are to live and how they are to behave. 21But select capable men from all the people—men who fear God, trustworthy men who hate dishonest gain—and appoint them as officials over thousands, hundreds, fifties and tens. 22Have 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.
