Leviticus 15:4-8

4Any bed the man with the discharge lies on will be unclean, and any furniture he sits on will be unclean.

5Anyone who touches his bed is to wash his clothes and bathe with water, and he will remain unclean until evening.

6Whoever sits on furniture that the man with the discharge was sitting on is to wash his clothes and bathe with water, and he will remain unclean until evening.

7Whoever touches the body of the man with a discharge is to wash his clothes and bathe with water, and he will remain unclean until evening.

8If the man with the discharge spits on anyone who is clean, he is to wash his clothes and bathe with water, and he will remain unclean until evening.
