Leviticus 12
The purification regulations after childbirth address the ritual dimension of the life-giving event without negative judgment on childbirth itself. After the birth of a son, the mother observes seven days of initial impurity (parallel to menstrual impurity) and thirty-three days of secondary purification — forty days total before full sanctuary access is restored; for a daughter, the periods are doubled (fourteen and sixty-six days, eighty total). On the eighth day, the son is circumcised — the covenant sign received on the first day of the mother's ritual cleanness. At the completion of the purification period, the mother brings a year-old lamb for a burnt offering and a dove or pigeon for a sin offering; if she cannot afford a lamb, two birds suffice. Luke 2:24 records that Mary brought the two-bird provision at Jesus' presentation, confirming the holy family's limited means. The chapter communicates the covenant's consistent provision: full restoration from every form of ritual impurity, accessible to every level of the community.
