On the other hand, a legally “unclean” person imparts his uncleanness to any thing, whereas a legally holy thing cannot confer its sanctity on an “unclean” person (Num 19:11, Num 19:13, Num 19:22). Legal sanctity is not so readily communicated as legal impurity. So the paths to sin are manifold: the paths to holiness one, and that one of difficult access [Grotius]. One drop of filth will defile a vase of water: many drops of water will not purity a vase of filth [Moore].
