Leviticus 12:1-8 describes the purification system for women that give birth in ancient Israel. This is a part of the ritual purity laws and gives instructions on how a new mother is to be purified of niddah (womb bleeding) uncleanness after childbirth. One puzzling aspect of childbirth purification is why must the mother wait only 40 days after giving birth to a boy, but 80 days for a girl? Also, she has to give a burnt, and sin offering even though that is typically for people who were recently healed of a bodily discharge disorder caused by sin (Lev 15:13-15;28-30). Having a child isn’t a sin or a disorder so why?
