Leviticus 15:8-11

“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.
