Exodus 18:21-22

21But you must also choose some other clever men to help you. They must be honest men who respect God. They must not want to take money from people. Choose these men to be officers with authority over groups of the people. They will be leaders of 1,000 people, or 100 people, or 50 people, or 10 people.

22They will be able to work as judges for the people, every day. They can decide the small quarrels. But if there is a difficult problem, they must bring it to you. That will make your work easier, because they will help you with the work.
