I know there are seven specific commandments to noachides but recently I was talking to a Rabbi who told me actually noachides have 420 commandments and the Jewish nation has 613. Can anyone point me to where I can find these 420 commandments he spoke of? Was he just making something up or is there somewhere I can read these? I am aware they are in the Torah but I would like to find them ordered if there is already a list someone is aware of.
I remember a PHD thesis (I think by Rabbi Lichtenstein, but I will have to find it) in which he stated that the 7 are actually categories, each of which consists of a number of different mitzvos (as far as making a link with the Torah goes). For example, there is the category of theft which can be broken down it individual mitzvos.
