The gemara brings statements saying that non-Jews cannot keep Shabbat or learn Torah. What are possible reasons for these prohibitions? A rule is brought that says how we know whether a commandment given to sons of Noach originally continued to be for everyone even after Jews received the Torah. Additionally, how do we know which ones were meant to be for only for Jews. Exceptions to the rule are brought to question the general rule and are resolved. Noach was permitted to eat meat but Adam was not allowed. The gemara questions this and through the questions a number of interesting issues are raised including, why did the snake seduce Adam and Chava? What is the status of meat that falls from the sky – can it assumed to be pure? Perhaps this is an image relating to heavenly voices vs. court rulings as referred to in other contexts in the gemara.
