The Noachide Laws
The Jewish Religion A Companion - Jacobs, p. 366
The seven laws given to Noach, the father of all mankind after the Flood.  The doctrine of the Noachide laws is based on the constant appeals in the Scriptures to Gentiles to behave justly and practice righteousness, implying that all human beings know either instinctively or by tradition what constitutes justice and righteousness.  These seven laws seem to be basic rules by which all humans are expected to live.  They constitute the Torah for the Gentile world.  Opinions are divided in the Rabbinic literature on the precise formulation of these seven principles but the accepted view of the seven is that they consist of the prohibition of idolatry, blasphemy, murder, adultery and incest (counted as one), robbery, the need to establish a proper system of justice; and the prohibition against eating flesh torn from a living animal.  A 'son of Noach' (ben Noach) is the name given to a Gentile.  He is obliged to keep the Noachide laws and if he does he belongs among 'the righteous of the nations of the world' who have a share in the World to Come.  Maimonides (Melachim 8:11) is unusual in qualifying this that the 'son of Noach' is obligated to keep the laws because he believes that they have been revealed by G-d, otherwise he belongs among 'the wise of the nations of the world' and not among the 'saints' of the nations of the world.
