Leviticus 15:5-10, 27

So if you touch the man’s bed, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. If you sit where the man with the discharge has sat, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. If you touch the man with the discharge, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. If the man spits on you, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. Any saddle blanket on which the man rides will be ceremonially unclean. If you touch anything that was under the man, you will be unclean until evening. You must wash your clothes and bathe yourself in water, and you will remain unclean until evening.

If any of you touch these things, you will be ceremonially unclean. You must wash your clothes and bathe yourself in water, and you will remain unclean until evening.
