Deuteronomy 1:15-18

15So I took the heads of your tribes, wise and experienced men, and set them as heads over you, commanders of thousands, commanders of hundreds, commanders of fifties, commanders of tens, and officers, throughout your tribes. 16And I charged your judges at that time, ‘Hear the cases between your brothers, and judge righteously between a man and his brother or the alien who is with him. 17You shall not be partial in judgment. You shall hear the small and the great alike. You shall not be intimidated by anyone, for the judgment is God’s. And the case that is too hard for you, you shall bring to me, and I will hear it.’ 18And I commanded you at that time all the things that you should do.
