Exodus 18:21-22

But you should also choose some of the people to be judges and leaders. “Choose good men you can trust—men who respect God. Choose men who will not change their decisions for money. Make these men rulers over the people. There should be rulers over 1000 people, 100 people, 50 people, and even over ten people. Let these rulers judge the people. If there is a very important case, then they can come to you and let you decide what to do. But they can decide the other cases themselves. In this way these men will share your work with you, and it will be easier for you to lead the people.
