Levítico 15

25 When 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. 26 Any 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. 27 Anyone who touches them has to wash their clothes, and wash themselves with water, and they will be unclean until the evening.
