Exodus 18:21-27New International Version (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. ²⁵ He chose capable men from all Israel and made them leaders of the people, officials over thousands, hundreds, fifties and tens. ²⁶ They served as judges for the people at all times. The difficult cases they brought to Moses, but the simple ones they decided themselves.

²⁷ Then Moses sent his father-in-law on his way, and Jethro returned to his own country.
