Exodus 18:21-22

And you will select from all the people men of ability, fearers of God, trustworthy men, haters of dishonest gain, and you will appoint such men over them as commanders of thousands, commanders of hundreds, commanders of fifties, and commanders of tens. And let them judge the people all the time, and every major issue they will bring to you, and every minor issue they will judge themselves. And so lighten it for yourself, and they will bear it with you.
