According to the Talmud (Makos 23b) "Moshe received 613 Mitzvos. They are 365 Lavim (negative commandments), corresponding to the days of the (solar) year, and 248 Mitzvos Aseh (positive commandments), corresponding to the limbs in a man".
This seems to beg the question — so why did God create the world such that there are 365 days to the year, and why 248 limbs in a man?
Does anyone know if there is a higher significance to these numbers?
