Deuteronomy 16:18, 19
Deuteronomy 16:18 NIV
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.
Deuteronomy 16:19 NIV
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.
