Wikipedia: Ten Commandments
The Ten Commandments, also known as the Decalogue, are a set of biblical principles relating to ethics and worship, which play a fundamental role in Judaism, Christianity, and Islam. The commandments include instructions to worship only God, to honour one’s parents, and to keep the sabbath, as well as prohibitions against idolatry, blasphemy, murder, adultery, theft, dishonesty, and coveting. Different religious groups follow different traditions for interpreting and numbering them.
The Ten Commandments are listed twice in the Hebrew Bible, first at Exodus 20:1–17, and then at Deuteronomy 5:6–21.
