Leviticus 15:5-8, 13, 21

Anyone who touches his bed must wash his clothes and bathe in water, and the person will be unclean until evening. Whoever sits on something that the person who discharges the fluid sat on must wash his clothes and bathe in water; he will be unclean until evening. Anyone who touches the person who discharges the body fluid must wash his clothes and bathe in water; he will be unclean until evening. “ ‘If the person who discharges the body fluid spits on someone who is clean, that person must wash his clothes and bathe in water; he will be unclean until evening.

“ ‘When a person who discharges a body fluid is made clean, he must count seven days for himself for his cleansing. He must wash his clothes and bathe his body in fresh water, and he will be clean.

Anyone who touches her bed must wash his clothes and bathe in water; that person will be unclean until evening.
