Deuteronomy 1:16-17

16“I commanded your judges at that time saying: ‘Hear cases between your brothers, and judge fairly between a man and his brother or the outsider with him.

17You must not show partiality in judgment —you must hear the small and the great alike. Fear no man, for the judgment is God’s. The case that is too hard for you, you shall bring to me and I will hear it.’
