And whatsoever the unclean person toucheth shall be unclean,
 &c.] Not the person unclean by sprinkling, or touching the water of purification, but the unclean person spoken of throughout the chapter, that was unclean by touching a dead body, bone, or grave; whatever that man touched, any vessel or thing, that was unclean also; or "whomsoever", any person, man or woman, for it respects both persons and things: 
 and the soul that toucheth it;
 that which the unclean person hath touched; or "him", the unclean person, whether the unclean person touched him, or he the unclean person, or touched anything he had touched, he was unclean; denoting the spreading and infectious nature of sin, and how much sin and sinners are to be avoided; see (  Leviticus 15:4-12 Leviticus 15:19 Leviticus 15:20 ) .
