Leviticus 15:17

And every garment, and every skin ,.... Or that is made of skin, which a man wears, or lies upon, see Leviticus 13:48 ,

whereon is the seed of copulation ; or on any other, for, as Gersom says, there is the same law concerning the rest of vessels, seeing this is a principal uncleanness, and defiles vessels; and perhaps the law makes mention of these, because it is more apt to be found on them:

shall be washed with water, and be unclean until the even ; see Judges 1:23 .
