Leviticus 15:8-10

American Standard Version

⁸ And if he that hath the issue spit upon him that is clean, then he shall wash his clothes, and bathe himself in water, and be unclean until the even. ⁹ And what ^[a]saddle soever he that hath the issue rideth upon shall be unclean. ¹⁰ And whosoever toucheth anything that was under him shall be unclean until the even: and he that beareth those things shall wash his clothes, and bathe himself in water, and be unclean until the even.
