Leviticus 15:5, 10-11

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

Whoever touches anything that has been under him shall be unclean until evening; and whoever carries those things shall wash his clothes and bathe in water, and be unclean until evening. Whomever the one with the discharge touches without rinsing his hands in water shall wash his clothes and bathe in water, and be unclean until evening.
