Deuteronomy 16:16-20

16“Each year every man in Israel must celebrate these three festivals: the Festival of Unleavened Bread, the Festival of Harvest, and the Festival of Shelters. On each of these occasions, all men must appear before the Lord your God at the place he chooses, but they must not appear before the Lord without a gift for him.

17All must give as they are able, according to the blessings given to them by the Lord your God.

18“Appoint judges and officials for yourselves from each of your tribes in all the towns the Lord your God is giving you. They must judge the people fairly.

19You must never twist justice or show partiality. Never accept a bribe, for bribes blind the eyes of the wise and corrupt the decisions of the godly.

20Let true justice prevail, so you may live and occupy the land that the Lord your God is giving you.
