Deuteronomy 1
16 Ref I charged your judges at that time, saying, Hear [the causes] between your brothers, and judge righteously between a man and his brother, and the foreigner who is living with him.
17 Ref You shall not show partiality in judgment; you shall hear the small and the great alike; you shall not be afraid of the face of man; for the judgment is God's: and the cause that is too hard for you, you shall bring to me, and I will hear it.
