Deuteronomy 16:14-20

14You shall rejoice in your feast, you and your son and your daughter and your male and female servants and the Levite and the stranger and the orphan and the widow who are within your city.

15Seven days you shall celebrate a 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 will be altogether joyful.

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 (Passover) and at the Feast of Weeks (Pentecost) and at the Feast of Booths (Tabernacles), and they shall not appear before the Lord empty-handed.

17Every man shall give as he is able, in accordance with the blessing which the Lord your God has given you.

18“You shall appoint judges and officers in all your cities (gates) which the Lord your God is giving you, according to your tribes, and they shall judge the people with righteous judgment.

19You shall not distort justice; you shall not be partial, and you shall not take a bribe, for a bribe blinds the eyes of the wise and perverts the words of the righteous.

20You shall pursue justice, and only justice [that which is uncompromisingly righteous], so that you may live and take possession of the land which the Lord your God is giving you.
