Exodus 18:24

22Let them judge the people at all times. It shall be that every great matter they shall bring to you, but every small matter they shall judge themselves. So shall it be easier for you, and they shall share the load with you.

23If you will do this thing, and God commands you so, then you will be able to endure, and all these people also will go to their place in peace.”

24So Moses listened to the voice of his father-in-law, and did all that he had said.

25Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens.

26They judged the people at all times. They brought the hard cases to Moses, but every small matter they judged themselves.
