Leviticus 15:4-8

4Any bed on which the man with the discharge lies and anything on which he sits will be ceremonially unclean.

5So if you touch the man’s bed, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening.

6If 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.

7If you touch the man with the discharge, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening.

8If the man spits on you, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening.
