Exodus 18:21-24 NIV

[21] But 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. [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. [23] If you do this and God so commands, you will be able to stand the strain, and all these people will go home satisfied.” [24] Moses listened to his father-in-law and did everything he said.
