DEUT857 Tzedek means justice, as in the famous verse, “Justice, justice shall you pursue” (Deuteronomy 16:20). The Torah's division of justice includes both procedural and substantive elements. That is, it demands that in court we ensure fairness by following specific procedures in judging people (“procedural justice”), and in society generally we must guarantee that there is a substantial safety net so that the poor, orphans, and widows get what they need to live, receive an education, and find a mate (“substantive justice”).
