Exodus 18:21-25

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. 23If you do this and God so commands, you will be able to stand the strain, and all these people will go home satisfied.” 24Moses listened to his father-in-law and did everything he said. 25He chose capable men from all Israel and made them leaders of the people, officials over thousands, hundreds, fifties and tens.
