Question:

My question is on the subject of cleanness of a mother after the birth of a male or female (Leviticus 12). The woman is unclean for seven days after a male birth, and after the birth of a female the mother is unclean for fourteen days. Why is there a difference between the birth of males and females?

Answer:

You write the word "cleanliness," when really it is "ritual purity." A woman's "impurity," or "tumah" in Hebrew, during her menstruation is a built-in component of her natural monthly cycle. Her status of "impurity" demonstrates her descent from a peak level of holiness, when she had the ability to conceive a precious new life through her union with her husband.

The status of "tumah" is not meant to imply sinfulness, degradation or inferiority. On the contrary, it emphasizes, in particular, the great level of holiness inherent in woman's G‑dly power to create and nurture a new life within her body, and the great holiness of a husband and wife's union, in general. Since a woman possesses this lofty potential, she, also bears the possibility of its void; hence her status as tameh, ritually impure. Since she experienced "the touch of death," so to speak, with the loss of potential life, as reflected by her menstruation, she enters this status of "impure."

After having given birth to a baby boy, a woman must wait a minimum of seven days before beginning her pure days; while after a baby girl is born, she must wait a minimum of fourteen days. Since the female child inherently carries a higher degree of holiness, due to her own biological, life creating capability, a greater void, or tumah, remains after her birth. Thus, the greater tumah after a baby girl's birth reflects her greater capacity for holiness (due to her creative powers) and necessitates the longer wait to remove this ritual impurity.

I hope this helps you.
