Childbirth

God told Moses to tell the Israelites that when a woman at childbirth bore a boy, she was to be unclean 7 days and then remain in a state of blood purification for 33, while if she bore a girl, she was to be unclean 14 days and then remain in a state of blood purification for 66 days. (Lev. 12:1–5.) Upon completing her period of purification, she was to bring a lamb for a burnt offering and a pigeon or a turtle dove for a sin offering, and the priest was to offer it as a sacrifice to make expiation on her behalf. (Lev. 12:6–7.) If she could not afford a sheep, she was to take two turtle doves or two pigeons, one for a burnt offering and the other for a sin offering. (Lev. 12:8.)

Skin Conditions

God told Moses and Aaron that when a person had a swelling, rash, discoloration, scaly affection, inflammation, or burn, it was to be reported to the priest, who was to examine it to determine whether the person was clean or unclean. (Lev. 13:1–44.) Unclean persons were to rend their clothes, leave their head bare, cover over their upper lips, call out, "Unclean! Unclean!" and dwell outside the camp. (Lev. 13:45–46.)

Clothing

Similarly, when a streaky green or red eruptive affection occurred in wool, linen, or animal skin, it was to be shown to the priest, who was to examine to determine whether it was clean or unclean. (Lev. 13:47–51.) If unclean, it was to be burned, but if the affection disappeared from the article upon washing, it was to be washed again and be clean. (Lev. 13:52–59.)
