Thanks for the link QED.

If I understand the article they laws were given down by God to Moses when Moses wrote the Torah. The laws were then further explained by men in the Talmud. This would be traditionist views

Would Jews who don’t believe Moses wrote the Torah believe that God gave the rules?
