Leviticus 12:1-13:5

The Lord spoke to Moses, saying: Speak to the Israelite people thus: When a woman at childbirth bears a male, she shall be unclean seven days; she shall be unclean as at the time of her menstrual infirmity. On the eighth day the flesh of his foreskin shall be circumcised. She shall remain in a state of blood purification for thirty-three days: she shall not touch any consecrated thing, nor enter the sanctuary until her period of purification is completed. If she bears a female, she shall be unclean two weeks as during her menstruation, and she shall remain in a state of blood purification for sixty-six days. On the completion of her period of purification, for either son or daughter, she shall bring to the priest, at the entrance of the Tent of Meeting, a lamb in its first year for a burnt offering, and a pigeon or a turtledove for a sin offering. He shall offer it before the Lord and make expiation on her behalf; she shall then be clean from her flow of blood. Such are the rituals concerning her who bears a child, male or female. If, however, her means do not suffice for a sheep, she shall take two turtledoves or two pigeons, one for a burnt offering and the other for a sin offering. The priest shall make expiation on her behalf, and she shall be clean. The Lord spoke to Moses and Aaron, saying: When a person has on the skin of his body a swelling, a rash, or a discoloration, and it develops into a scaly affection on the skin of his body, it shall be reported to Aaron the priest or to one of his sons, the priests. The priest shall examine the affection on the skin of his body: if hair in the affected patch has turned white and the affection appears to be deeper than the skin of his body, it is a leprous affection; when the priest sees it, he shall pronounce him unclean. But if it is a white discoloration on the skin of his body which does not appear to be deeper than the skin and the hair in it has not turned white, the priest shall isolate the affected person for seven days. On the seventh day the priest shall examine him, and if the affection has remained unchanged in color and the disease has not spread on the skin, the priest shall isolate him for another seven days.
