Leviticus 11:28

And he that takes of their dead bodies shall wash his garments, and shall be unclean till evening: these are unclean to you.

And he that beareth the carcase of them shall wash his clothes, and be unclean until the even: they are unclean unto you.

He who carries their carcass shall wash his clothes, and be unclean until the evening. They are unclean to you.
