Deuteronomy 16:18-22

Judges and officers shalt thou make thee in all thy gates, which the LORD thy God giveth thee, throughout thy tribes: and they shall judge the people with just judgment. Thou shalt not wrest judgment; thou shalt not respect persons, neither take a gift: for a gift doth blind the eyes of the wise, and pervert the words of the righteous. That which is altogether just shalt thou follow, that thou mayest live, and inherit the land which the LORD thy God giveth thee. Thou shalt not plant thee a grove of any trees near unto the altar of the LORD thy God, which thou shalt make thee. Neither shalt thou set thee up any image; which the LORD thy God hateth.
