Leviticus 15:4-8

4“Every bed on which he who has the discharge lies will become unclean, and everything he sits on will be unclean.

5Whoever touches his bed is to wash his clothes and bathe himself in water, and be unclean until the evening.

6Whoever sits on anything on which the man who has the discharge sat is to wash his clothes and bathe himself in water, and be unclean until the evening.

7Whoever touches the body of the one who has the discharge is to wash his clothes and bathe himself in water, and be unclean until the evening.

8Or if the one who has the discharge spits on someone who is clean, then he also is to wash his clothes and bathe himself in water, and be unclean until the evening.
