Leviticus 15:24-26

²⁴If a man has sex with a woman during that time and some of the menstrual blood touches him, no one should touch him for seven days, and no one should touch the bed that he lies on.

²⁵When a woman has a vaginal discharge of blood for ◄many days/a long time►, which is not her monthly flow of blood, or if her flow of blood continues after her monthly flow ends, no one should touch her until it stops.

²⁶And no one should touch the bed that she lies on or anything that she sits on while that flow of blood continues, just like during her monthly menstrual period.
