Purifying our ways and ourselves[1]
דבר אל-בני ישראל לאמר אשה כי תזירע וילדה זכר וטמאה שבעת ימים כימי נדת דותה תטמא: וביום השמיני ימול בשר ערלתו: ושלשים יום ושלשת ימים תשב בדמי טהרה וגו’
Speak to the Children of Israel, saying: A woman who conceives and gives birth to a baby boy will be ritually impure for seven days; like the days of her monthly period she will be impure. On the eighth day [the baby’s] flesh shall be circumcised. For thirty-three days [the mother] shall remain in her state of purity…[2]
This week’s parsha deals with many types of ritual impurity. It begins by describing what happens when a woman gives birth to a baby boy. She becomes impure for a week, upon which she can then immerse in a mikveh, becoming pure again. Her baby has a bris milah on the eighth day. The Torah then says that for thirty-three days the woman has a presumed status of ritual purity. The Torah then proceeds to describe what happens when she gives birth to a baby girl. What’s unusual is the Torah mentions the mitzvah of bris milah here, of all places. It seemingly has no relevance to a parsha dealing with ritual purity. Why is this the place to put it? As well, why was this mitzvah sandwiched in between the verses describing the woman’s ritual purity status, interrupting the flow of the verses?
