Deuteronomy 16:18-20

Appoint judges and officers for your tribes in every town the LORD your God is giving you; they must judge the people fairly. Do not judge unfairly or take sides. Do not let people pay you to make wrong decisions, because that kind of payment makes wise people seem blind, and it changes the words of good people. Always do what is right so that you will live and always have the land the LORD your God is giving you.
