Leviticus 15:5-8, 13, 21

And whoever touches his bed shall wash his clothes and bathe in water, and be unclean until evening. He who sits on anything on which he who has the discharge sat shall wash his clothes and bathe in water, and be unclean until evening. And he who touches the body of him who has the discharge shall wash his clothes and bathe in water, and be unclean until evening. If he who has the discharge spits on him who is clean, then he shall wash his clothes and bathe in water, and be unclean until evening.

‘And when he who has a discharge is cleansed of his discharge, then he shall count for himself seven days for his cleansing, wash his clothes, and bathe his body in running water; then he shall be clean.

Whoever touches her bed shall wash his clothes and bathe in water, and be unclean until evening.
