Exodus 18:21-22

Moreover thou shalt consider out of all the people men of virtue, such as fear God, men of truth, hating covetousness, and place princes over them, of thousands, of hundreds, of fifties, and of tens. And let them judge the people at all seasons; and it shall be that every great matter they shall bring unto thee, but every small matter they shall judge, so shall it be easier for thyself, and they shall bear the burden with thee.
