Leviticus 15:4-11, 25-27

“Every bed on which he lies is ritually unclean, everything on which he sits is unclean. If someone touches his bed or sits on anything he’s sat on, or touches the man with the discharge, he has to wash his clothes and bathe in water; he remains unclean until evening. “If the man with the discharge spits on someone who is clean, that person has to wash his clothes and bathe in water; he remains unclean until evening. Every saddle on which the man with the discharge rides is unclean. Whoever touches anything that has been under him becomes unclean until evening. Anyone who carries such an object must wash his clothes and bathe with water; he remains unclean until evening. If the one with the discharge touches someone without first rinsing his hands with water, the one touched must wash his clothes and bathe with water; he remains unclean until evening.

“If a woman has a discharge of blood for many days, but not at the time of her monthly period, or has a discharge that continues beyond the time of her period, she is unclean the same as during the time of her period. Every bed on which she lies during the time of the discharge and everything on which she sits becomes unclean the same as in her monthly period. Anyone who touches these things becomes unclean and must wash his clothes and bathe in water; he remains unclean until evening.
