Deuteronomy 16:18-22

Appoint judges and officials for each of your tribes in every town the LORD your God is giving you, and they shall judge the people fairly. Do not pervert justice or show partiality. Do not accept a bribe, for a bribe blinds the eyes of the wise and twists the words of the innocent. Follow justice and justice alone, so that you may live and possess the land the LORD your God is giving you. Do not set up any wooden Asherah pole beside the altar you build to the LORD your God, and do not erect a sacred stone, for these the LORD your God hates.
