Leviticus 15:5

And whosoever toucheth his bed ,.... Is unclean. According to the Misnah F24 Zabim, ut supra. (c. 2. sect. 4.) , a bed defiles a man seven ways, so as to defile garments; standing, sitting, lying, hanging, and leaning, and by touching, and by bearing:

shall wash his clothes, and bathe himself in water ; in forty seahs of water, as the Targum of Jonathan:

and be unclean until the even ; be unfit for conversation with other men till the even, though both his body and clothes are washed.
