Leviticus 15:6

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 .

Whoever sits on anything that the man with a discharge sat on must wash their clothes and bathe with water, and they will be unclean till evening.

And he that sitteth on any thing whereon he sat that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.
