Leviticus 15:5-8, 13, 21

And anyone who touches his bed shall wash his clothes and bathe himself in water and be unclean until the evening. And whoever sits on anything on which the one with the discharge has sat shall wash his clothes and bathe himself in water and be unclean until the evening. And whoever touches the body of the one with the discharge shall wash his clothes and bathe himself in water and be unclean until the evening. And if the one with the discharge spits on someone who is clean, then he shall wash his clothes and bathe himself in water and be unclean until the evening.

“And when the one with a discharge is cleansed of his discharge, then he shall count for himself seven days for his cleansing, and wash his clothes. And he shall bathe his body in fresh water and shall be clean.

And whoever touches her bed shall wash his clothes and bathe himself in water and be unclean until the evening.
