What does Leviticus 15:11 mean?

And whomsoever he that hath the issue toucheth, without having rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.

And whomsoever he toucheth that hath the issue, and hath not rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.

And whomsoever he that hath the issue toucheth, without having rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.

And anyone on whom the unclean man puts his hands, without washing them in water, is to have his clothing washed and his body bathed in water and be unclean till evening.

`And anyone against whom he cometh who hath the issue (and his hands hath not rinsed with water) hath even washed his garments, and bathed with water, and been unclean till the evening.

Every person whom such a one shall touch, not having washed his hands before, shall wash his clothes: and being washed with water, shall be unclean until the evening.

And whomsoever he toucheth who hath the flux and hath not rinsed his hands in water — he shall wash his garments, and bathe in water, and be unclean until the even.
