Unclean women:

A woman is unclean for seven days after giving birth to a boy. On the eighth day, the boy will be circumcised, and the mother will spend the next thirty-three days “in the blood of her purifying.” Whatever that means. During that time, she is not allowed to touch anything holy or go to the church.
If she has a daughter, she will be unclean for two weeks and spend sixty-six days in the blood of her purifying. Because, of course, girls are evil.

After her purifying is complete, she will bring a lamb and a pigeon or turtledove to the priest for a sin offering. “Then she shall be clean from the flow of her blood.”
