Leviticus 15:4-9

Every bed on which the one with the discharge lies shall be unclean, and everything on which he sits shall be unclean. 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 any saddle on which the one with the discharge rides shall be unclean.
