Deuteronomy 16:18-20

“You shall appoint judges and officers in all your towns that the LORD your God is giving you, according to your tribes, and they shall judge the people with righteous judgment. You shall not pervert justice. You shall not show partiality, and you shall not accept a bribe, for a bribe blinds the eyes of the wise and subverts the cause of the righteous. Justice, and only justice, you shall follow, that you may live and inherit the land that the LORD your God is giving you.
