The Ten Commandments, also known as the Decalogue, from the Greek words δέκα (ten) and λόγος (words), are a set of ethical and worship principles, which play an important role in Judaism and Christianity. They include instructions on how to worship only one God and keep the Sabbath, as well as prohibitions against idolatry, murder, theft, dishonesty, and adultery. Different religious groups follow different traditions in how to interpret and list them.

The Ten Commandments appear twice in the Hebrew Bible: in the books of Exodus and Deuteronomy. According to the story told in the book of Exodus, God wrote these commands on two stone tablets, which he gave to Moses on Mount Sinai; According to the story, when he was coming down from the mountain, he saw the people who were worshiping a golden calf and, furious, he broke them. Later, he asked God to forgive the people and seal with them a "covenant" (pact or alliance); Then, the Lord ordered Moses to take two stone slabs and on them were written the Ten Commandments of the covenant, rebuking him that "they must not tolerate disobedience."
