Emor: Chapter 15

"Then it shall be seven days under its mother"


We are told that an animal accepted for a burnt offering shall be at least seven days old so that it will have experienced one Shabbat. We learn about why man must undergo one Shabbat before his circumcision. The two bloods spoken of are the blood of the Pascal sacrifice and the blood of circumcision, and the blood of circumcision is itself two bloods, through which one attains the life of the World to Come.
