Exodus 18:22-25

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.

23If you agree with my idea, and if God commands you to do it, it will help you. The work will not be too hard for you. And all these people will go home happily.’

24Moses listened to Jethro and he did everything that Jethro had said.

25Moses chose wise men from all the Israelites. He made them officers to lead 1,000 people, or 100 people, or 50 people, or 10 people.
