Leviticus 15:8

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.

11 Whoever he who has the issue touches, without having rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.
