Deuteronomy 16:16-20

16Three times a year all your men must appear before the Lord your God at the place he will choose: at the Festival of Unleavened Bread, the Festival of Weeks and the Festival of Tabernacles. No one should appear before the Lord empty-handed:

17Each of you must bring a gift in proportion to the way the Lord your God has blessed you.

18Appoint 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.

19Do 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.

20Follow justice and justice alone, so that you may live and possess the land the Lord your God is giving you.
