Famous fowl fidelity[1]
ובמלאת ימי טהרה לבן או לבת תביא כבש בן-שנתו לעלה ובן-יונה או תר לחטאת אל-פתח אהל מועד אל-הכהן
At the completion of her days of purity for a boy or a girl, she shall bring to the entrance of the Tent of Meeting, to the Kohen, a year-old sheep for an Olah, and a dove or a turtledove for a Chatas[2]
A mitzvah unique to women is the offerings brought after giving birth. A woman must bring a year-old sheep for an Olah offering, and a bird for a Chatas offering. The Torah only allows two types of birds for offerings: turtledoves or doves. In the entire Torah, turtledoves are always mentioned before doves, except in this one instance. The Torah says she can bring a dove or a turtledove. Why here is the usual order switched?
