Exodus 18:13-14, 19-26

And so it was, on the next day, that Moses sat to judge the people; and the people stood before Moses from morning until evening. So when Moses’ father-in-law saw all that he did for the people, he said, “What is this thing that you are doing for the people? Why do you alone sit, and all the people stand before you from morning until evening?”

Listen now to my voice; I will give you counsel, and God will be with you: Stand before God for the people, so that you may bring the difficulties to God. And you shall teach them the statutes and the laws, and show them the way in which they must walk and the work they must do. Moreover you shall select from all the people able men, such as fear God, men of truth, hating covetousness; and place such over them to be rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens. And let them judge the people at all times. Then it will be that every great matter they shall bring to you, but every small matter they themselves shall judge. So it will be easier for you, for they will bear the burden with you. If you do this thing, and God so commands you, then you will be able to endure, and all this people will also go to their place in peace.” So Moses heeded the voice of his father-in-law and did all that he had said. And Moses 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. So they judged the people at all times; the hard cases they brought to Moses, but they judged every small case themselves.
