Leviticus 15:25-29

²⁵When a woman has a discharge of blood for several days when it's not the time for her period, or if it continues past her period, she will be unclean for the whole time she is bleeding, not just for the days of her period.

²⁶Any bed she lies on or anything she sits on while she has her discharge will be unclean, just as her bed is during her period.

²⁷Anyone who touches them has to wash their clothes, and wash themselves with water, and they will be unclean until the evening.

²⁸Once the woman's discharge has healed, she must allocate seven days for her cleaning process, wash her clothes, and wash herself in fresh water, and she shall be clean.

²⁹On the eighth day she must take two turtledoves or two young pigeons, come before the Lord at the entrance to the Tent of Meeting, and give them to the priest.
