Exodus 18:21-22

Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating unjust gain; 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 seasons: and it shall be, that every great matter they shall bring unto thee, but every small matter they shall judge themselves: so shall it be easier for thyself, and they shall bear the burden with thee.
