The [[Talmud]] (tractate [[Sanhedrin (tractate)|Sanhedrin]] 56a/b, quoting [[Tosefta]] Sanhedrin 9:4) states that the instruction to not eat "flesh with the life" was given to Noah, and that [[Adam and Eve]] had already received six other commandments. The remaining six are exegetically derived from a seemingly superfluous sentence in Genesis 2:16.<ref>http://www.wikinoah.org/index.php/Noahide_Laws#The_Seven_Laws</ref>
Yahadut exists to teach the Noahite Covenant to all nations of the creation.
