Leviticus 15:5-11, 27

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. Whoever touches anything that was under him shall be unclean until evening. He who carries any of those things shall wash his clothes and bathe in water, and be unclean until evening. And whomever the one who has the discharge touches, and has not rinsed his hands in water, he shall wash his clothes and bathe in water, and be unclean until evening.

Whoever touches those things shall be unclean; he shall wash his clothes and bathe in water, and be unclean until evening.
