Deuteronomy 16:16-20

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

Everyone shall give as he is able, in accordance with the blessing of the Lord your God which He has given you.

“You shall appoint for yourself judges and officers in all your towns which the Lord your God is giving you, according to your tribes, and they shall judge the people with righteous judgment.

You shall not distort justice, you shall not show partiality; and you shall not accept a bribe, because a bribe blinds the eyes of the wise and distorts the words of the righteous.

Justice, and only justice, you shall pursue, so that you may live and possess the land which the Lord your God is giving you.
