Leviticus 15:7

4 Every bed whereon he who has the issue lies shall be unclean; and everything whereon he sits shall be unclean.

5 Whoever touches his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.

6 He who sits on anything whereon he who has the issue sat shall wash his clothes, and bathe himself in water, and be unclean until the even.

7 He who touches the flesh of him who has the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.

8 If he who has the issue spit on him who is clean, then he shall wash his clothes, and bathe himself in water, and be unclean until the even.

9 Whatever saddle he who has the issue rides on shall be unclean.

10 Whoever touches anything that was under him shall be unclean until the even: and he who bears those things shall wash his clothes, and bathe himself in water, and be unclean until the even.
