Deuteronomy

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.

And the Lord said unto Moses, Gather unto me seventy men of the elders of Israel, whom thou knowest to be the elders of the people, and officers over them; and bring them unto the tabernacle of the congregation, that they may stand there with thee.

Do ye indeed speak righteousness, O congregation? do ye judge uprightly, O ye sons of men?

Judges and officers shalt thou make thee in all thy gates, which the Lord thy God giveth thee, throughout thy tribes: and they shall judge the people with just judgment.

And they judged the people at all seasons: the hard causes they brought unto Moses, but every small matter they judged themselves.
