Question: “What are the Noahide Laws, and are they biblical?”

Answer: The Noahide Laws are seven ancient laws that many people view as the basis of civilized society. They govern morality and represent the “bare minimum” of what God expects of humanity. They are called the “Noahide” laws because they are thought to have been given in their fullness to Noah after the flood. They are also called the Noachian laws, the Seven Laws of Noah, or the Seven Commands for Noah’s Sons (in Hebrew, Sheva Mitzvot B’nei Noach).
