In the text of the Hebrew Bible (the Torah), Moses explicitly commanded the Israelites to strictly observe the covenantal laws, moral statutes, and civil judgments given by God at Mount Sinai, summarized in Deuteronomy 6:4-5.
Historical-critical scholars emphasize that Moses' mission was to establish a highly structured, law-observant community that rejected ancient polytheism and maintained a unique identity through dietary codes (Kosher), Sabbath observance, and sacrificial rituals. Both Jewish and Islamic traditions view Moses as a lawgiver whose primary instruction was obedience to divine law.
