Leviticus 15:1-12

The LORD also said to Moses and Aaron, “Say to the people of Israel: ‘When a fluid comes from a person’s body, the fluid is unclean. It doesn’t matter if the fluid flows freely or if it is blocked from flowing; the fluid will make him unclean. This is the way the fluid makes him unclean: “ ‘If the person who discharges the body fluid lies on a bed, that bed becomes unclean, and everything he sits on becomes unclean. 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. Everything on which the person who is unclean sits when riding will become unclean. Anyone who touches something that was under him will be unclean until evening. And anyone who carries these things must wash his clothes and bathe in water; he will be unclean until evening. “ ‘If the person who discharges a body fluid has not washed his hands in water and touches another person, that person must wash his clothes and bathe in water; he will be unclean until evening. “ ‘If a person who discharges a body fluid touches a clay bowl, that bowl must be broken. If he touches a wooden bowl, that bowl must be washed in water.
