Leviticus 15:12

And the vessel of earth that he toucheth which hath an issue shall be broken,.... That it might not be made use of afterwards; which was ordered, that they might be careful what they touched who were in such circumstances: according to Gersom an earthen vessel received no uncleanness but from the middle, though he owns the law does not distinguish between the middle and the outside; wherefore Jarchi is of opinion, that if the back or outside of it was touched, it was unclean, and to be broken:

and every vessel of wood shall be rinsed in water; and after that be used: what should be the reason why an earthen vessel defiled by touching should be broken, and a wooden vessel defiled in the same way should not, but be rinsed and cleansed, when an earthen vessel might as well be rinsed and fit for use as that, is not easy to say; it depended upon the will of the lawgiver: according to Ainsworth, the one may signify the destruction of reprobate persons, the other the cleansing of penitent sinners.
