Leviticus

And if a woman have an issue of her blood many days out of the time of her separation, or if it run beyond the time of her separation; all the days of the issue of her uncleanness shall be as the days of her separation: she shall be unclean.

But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean.

And when the days of her purification according to the law of Moses were accomplished, they brought him to Jerusalem, to present him to the Lord;

(As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;)

Then said Haggai, If one that is unclean by a dead body touch any of these, shall it be unclean? And the priests answered and said, It shall be unclean.
