The Lord spoke to Moses saying, “Speak to the Children of Israel regarding the rituals concerning childbirth of a boy.The mother shall be in the state of purification for seven days. Upon the eighth day the flesh of a male baby’s foreskin is to be circumcised. For thirty-three days, the mother shall be in a state of purification. At the end of this time, she is to make offerings at the Tent of Appointed Meeting.” G-d then spoke to Moses and to Aaron, saying, “When a person has a swelling, rash, burn, scaly eruption discoloration, or any other kind of distortion of the skin, it shall be reported to Aaron the priest or to one of his sons. The priest shall examine the skin for the contagious disease of leprosy and pronounce the person clean or unclean.
