46 This is the law of the beasts, and of the fowl, and of every living creature that moveth in the waters, and of every creature that creepeth upon the earth;
47 To make a difference between the unclean and the clean, and between the beast that may be eaten and the beast that may not be eaten.
Leviticus 12 Intro: The laws of purification.
1 And the Lord spake unto Moses, saying,
2 Speak unto the children of Israel, saying, If a woman have conceived seed, and borne a man child, then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.
3 And in the eighth day, the man child shall be circumcised.
4 And she shall then continue in the time of her purifying which shall be three and thirty days; she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled.
5 But if she bear a maid child, she shall be unclean two weeks, as in her separation; and she shall continue in the time of her purifying threescore and six days.
6 And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb of the first year for a burnt offering, and a young pigeon, or a turtle dove, for a sin offering, unto the door of the tabernacle of the congregation, unto the priest;
7 Who shall offer it before the Lord, and make an atonement for her; and she shall be cleansed from the issue of her blood. This is the law for her that hath borne a male or a female.
8 And if she be not able to bring a lamb, then she shall bring two turtles, or two young pigeons; the one for the burnt offering, and the other for a sin offering; and the priest shall make an atonement for her, and she shall be clean.
