Deuteronomy 16:16-20

16“1Three times in a year all your males shall appear before the Lord your God in the place which He chooses, at the Feast of Unleavened Bread and at the Feast of Weeks and at the Feast of Booths, and 2they shall not appear before the Lord empty-handed. 17Every man 3shall give as he is able, according to the blessing of the Lord your God which He has given you.

18“You shall appoint for yourself judges and officers in all your 4towns which the Lord your God is giving you, according to your tribes, and they shall judge the people with righteous judgment. 195You shall not distort justice; 6you shall not 7be partial, and 8you shall not take a bribe, for a bribe blinds the eyes of the wise and perverts the words of the righteous. 20Justice, and only justice, you shall pursue, that 9you may live and possess the land which the Lord your God is giving you.
