Exodus 18:22-25

22Let them be the ones who usually settle disagreements among the people. They should bring all important cases to you, but they should settle all minor cases themselves. Make it easier for yourself by letting them help you.

23If God commands you, and you do this, you will be able to continue your work, and all these people will have their disagreements settled so that they can go home.”

24Moses listened to his father-in-law and did everything he said.

25Moses chose capable men from all the Israelites and put them in charge of groups of 1,000, or 100, or 50, or 10 people.
