This week's sugya discusses the sources for the age of Bar Mitzvah or Bas Mitzvah. One of the sources is found in ParshasVayishlach where Shimon and Levi are referred to as "Ish". We also discuss the age of adulthood with regards to Bnei Noach, and how it may affect Bnei Yisroel as well. The sugya also highlights an interesting debate amongst the mefarshim as to the calculation of Shimon and Levi's ages at that time.
