Deuteronomy 1:16-18

16“Then I commanded your judges at that time, saying, ‘Hear the cases between your brethren, and judge righteously between a man and his brother or the stranger who is with him.

17You shall not show partiality in judgment; you shall hear the small as well as the great; you shall not be afraid in any man’s presence, for the judgment is God’s. The case that is too hard for you, bring to me, and I will hear it.’

18And I commanded you at that time all the things which you should do.
