Deuteronomy 16
18 Ref You are to make judges and overseers in all your towns which the Lord your God gives you, for every tribe: and they are to be upright men, judging the people in righteousness.
19 Ref You are not to be moved in your judging by a man's position, you are not to take rewards; for rewards make the eyes of the wise man blind, and the decisions of the upright false.
20 Ref Let righteousness be your guide, so that you may have life, and take for your heritage the land which the Lord your God is giving you.
