Non-Jews came to Jerusalem to take vows to follow the Sheva Mitzvot Benai Noach, and some Arabs talk of joining the Jewish people. As seen on http://www.shabbat.com/Arutz Sheva.
The Seven Laws of Noah (Sheva mitzvot B’nei Noach) form the major part of the Noachide Laws, or Noahide Code. This code is a set of moral imperatives that, according to the Talmud, were given by God as a binding set of laws for the “children of Noah” – that is, all of humankind. According to religious Judaism, any non-Jew who lives according to these laws is regarded as a Righteous Gentile, and is assured of a place in the world to come (Olam Haba), the final reward of the righteous. Adherents are often called “B’nei Noach” (Children of Noah) or “Noahides” and may often network in Jewish synagogues.
The seven laws listed by the Tosefta and the Talmud are:
Prohibition of Idolatry
Prohibition of Murder
Prohibition of Theft
Prohibition of Sexual immorality
Prohibition of Blasphemy
Prohibition of eating flesh taken from an animal while it is still alive
Establishment of courts of law
The Noachide Laws comprise the six laws which were given to Adam in the Garden of Eden, according to the Talmud’s interpretation of Gen 2:16, and a seventh one, which was added after the Flood of Noah. Later, at the Revelation at Sinai, the Seven Laws of Noah were re-given to humanity and embedded in the 613 Laws given to the Children of Israel along with the Ten Commandments, which are part of, and not separate from, the 613 mitzvot. These laws are derived from the Torah. According to religious Judaism, the 613 mitzvot or “commandments” given in the written Torah, as well as their reasonings in the oral Torah, were only issued to the Jews and are therefore binding only upon them, having inherited the obligation from their ancestors. At the same time, at Mount Sinai, the Children of Israel were given the obligation to teach other nations the embedded Noachide Laws. These laws also affect Jewish law in a number of ways.
