12:3 On the eighth day the flesh of his foreskin shall be circumcised
This chapter deals with the laws of purity applying to a woman after childbirth. In this context, the Bible also mentions the law of circumcision, the removal of the baby boy’s foreskin on the eighth day of his life. Circumcision was the first commandment given to Avraham, as detailed in Sefer Bereishit chapter 17. That chapter begins with the covenant Hashem makes with Avraham, promising that He will be an everlasting God to Avraham and his descendants, that Avraham will merit numerous offspring, and that Hashem will give them the Land of Israel as an eternal inheritance. To this very day, the circumcision of a male descendant of Avraham draws the new child into the covenant with Hashem, and serves as a constant reminder of God’s promise to remain with His people and give them Eretz Yisrael.
