Deuteronomy 16:18

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.

Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an awl; and he shall serve him for ever.

So I took the chief of your tribes, wise men, and known, and made them heads over you, captains over thousands, and captains over hundreds, and captains over fifties, and captains over tens, and officers among your tribes. And I charged your judges at that time, saying, Hear the causes between your brethren, and judge righteously between every man and his brother, and the stranger that is with him. Ye shall not respect persons in judgment; but ye shall hear the small as well as the great; ye shall not be afraid of the face of man; for the judgment is God's: and the cause that is too hard for you, bring it unto me, and I will hear it.

And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and inquire; and they shall show thee the sentence of judgment:

Then both the men, between whom the controversy is, shall stand before the LORD, before the priests and the judges, which shall be in those days;

Then thy elders and thy judges shall come forth, and they shall measure unto the cities which are round about him that is slain:

Of which, twenty and four thousand were to set forward the work of the house of the LORD; and six thousand were officers and judges:

Of the Izharites, Chenaniah and his sons were for the outward business over Israel, for officers and judges.
