Leviticus 15:4-9

Every bed is unclean on which he who has the discharge lies, and everything on which he sits shall be unclean. 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. Any saddle on which he who has the discharge rides shall be unclean.
