Deuteronomy 1

16 And I charged your judges at that time, saying, Hear causes between your brethren, and judge rightly between a man and his brother, and the stranger that is with him. 17 Thou shalt not have respect to persons in judgment, thou shalt judge small and great equally; thou shalt not shrink from before the person of a man, for the judgment is God’s; and whatsoever matter shall be too hard for you, ye shall bring it to me, and I will hear it.
