Deuteronomy 1:15-17

15So I took the heads of your tribes, wise men, and known, and made them heads over you, captains of thousands, and captains of hundreds, and captains of fifties, and captains of tens, and officers, according to your tribes.

16And I charged your judges at that time, saying, Hear the causes between your brethren, and judge righteously between a man and his brother, and the stranger that is with him.

17Ye shall not respect persons in judgment; ye shall hear the small and the great alike; 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 ye shall bring unto me, and I will hear it.
