Exodus 18:19-27 (King James Version)
19 Hearken now unto my voice, I will give thee counsel, and God shall be with thee: Be thou for the people to God-ward, that thou mayest bring the causes unto God: 20 And thou shalt teach them ordinances and laws, and shalt shew them the way wherein they must walk, and the work that they must do. 21 Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating covetousness; and place such over them, to be rulers of thousands, and rulers of hundreds, rulers of fifties, and rulers of tens: 22 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. 23 If thou shalt do this thing, and God command thee so, then thou shalt be able to endure, and all this people shall also go to their place in peace. 24 So Moses hearkened to the voice of his father in law, and did all that he had said. 25 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. 26 And they judged the people at all seasons: the hard causes they brought unto Moses, but every small matter they judged themselves. 27 And Moses let his father in law depart; and he went his way into his own land.
