Leviticus 12:2
12:2 Speak unto the children of Israel, saying, If a woman have
     conceived seed, and born a man child: then she shall be
     unclean {a} seven days; according to the days of the
     separation for her infirmity shall she be unclean.

     (a) So that her husband for that time could not have
         relations with her.

Leviticus 12:4
12:4 And she shall then continue in the blood of her purifying
     three {b} and thirty days; she shall touch no {c} hallowed
     thing, nor come into the {d} sanctuary, until the days of
     her purifying be fulfilled.

     (b) Besides the first seven days.
     (c) As sacrifice, or such like.
     (d) That is, into the court gate till after forty days.

Leviticus 12:5
12:5 But if she bear a maid child, then she shall be unclean two
     {e} weeks, as in her separation: and she shall continue in
     the blood of her purifying threescore and six days.

     (e) Twice as long as if she gave birth to a boy.

Leviticus 12:6
12:6 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
     turtledove, for a sin offering, unto the door of the {f}
     tabernacLe of the congregation, unto the priest:

     (f) Where the burnt offerings were wont to be offered.
