Leviticus 15:17

And every skin. — That is, everything which a man wears or lies upon made of skin, in contradistinction to the ordinary garments made of stuffs (see Leviticus 13:48) with which it is associated. Any one of these thus defiled was cleansed by washing. It is from this circumstance that the apostle borrows the expression “hating even the garments spotted by the flesh” (Jude 1:23).
