Deuteronomy 1:16-17

And 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 sojourner that is with him. Ye 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.
