Deuteronomy 16:14-20

14And you shall rejoice in your feast, you and your son and your daughter, your male servant and your female servant and the Levite, the stranger and the fatherless and the widow, who are within your gates.

15Seven days you shall keep a sacred feast to the Lord your God in the place which the Lord chooses, because the Lord your God will bless you in all your produce and in all the work of your hands, so that you surely rejoice.

16“Three times a year all your males shall appear before the Lord your God in the place which He chooses: at the Feast of Unleavened Bread, at the Feast of Weeks, and at the Feast of Tabernacles; and they shall not appear before the Lord empty-handed.

17Every man shall give as he is able, according to the blessing of the Lord your God which He has given you.

18“You shall appoint judges and officers in all your gates, which the Lord your God gives you, according to your tribes, and they shall judge the people with just judgment.

19You shall not pervert justice; you shall not show partiality, nor take a bribe, for a bribe blinds the eyes of the wise and twists the words of the righteous.

20You shall follow what is altogether just, that you may live and inherit the land which the Lord your God is giving you.
