'Separation' in the Bible

Speak unto the children of Israel, saying, If a woman conceive seed, and bear a male, then she shall be unclean seven days; as in the days of the separation of her infirmity shall she be unclean.

And if she bear a female, then she shall be unclean two weeks, as in her separation; and she shall continue sixty-six days in the blood of her cleansing.

And if a woman have a flux, and her flux in her flesh be blood, she shall be seven days in her separation, and whoever toucheth her shall be unclean until the even.

And everything that she lieth upon in her separation shall be unclean; and everything that she sitteth upon shall be unclean.

And if a man lie with her at all, and the uncleanness of her separation come upon him, he shall be unclean seven days; and every bed whereon he lieth shall be unclean.

And if a woman have her flux of blood many days out of the time of her separation, or if she have the flux beyond the time of her separation, all the days of the flux of her uncleanness shall she be as in the days of her separation: she is unclean.

Every bed whereon she lieth all the days of her flux shall be unto her as the bed of her separation; and every object on which she sitteth shall be unclean, according to the uncleanness of her separation.

and for a woman who is sick in her separation, and for him that hath his flux; for the man and for the woman, and for him that lieth with her that is unclean.

And thou shalt not approach a woman in the separation of her uncleanness to uncover her nakedness.

And ye shall make a separation between the clean beast and the unclean, and between the unclean fowl and the clean, and ye shall not make yourselves an abomination by beast, or by fowl, or by anything that creepeth on the ground which I have separated for you, declaring it as unclean.
