Containers made from wood, leather, or bone, e.g., a kneading trough, a drinking pouch, or the like, are susceptible to ritual impurity according to Scriptural Law. Keilim made from wood, leather, or bone that are flat, e.g., tablets, a chair, a leather mat on which one eats, and the like, by contrast, are susceptible to ritual impurity only according to Rabbinic Law, as implied by the phrase: "From all wooden keilim... or sackcloth." According to the Oral Tradition, it was taught: "Just as the sackcloth which is susceptible to ritual impurity has a receptacle, so too, keilim made from all the other substances mentioned must have a receptacle. keilim made from bone are governed by the same laws as those made from wood in all matters. When does the statement that flat utensils made from these substances are susceptible to impurity only according to Rabbinic Law apply? With regard to all impurities other than the impurity contracted from a support that contracted impurity from a zav. With regard to the impurity resulting from a support that contracted impurity from a zav or others like him, they contract impurity according to Scriptural Law, as implied by Leviticus 15:4: "Any surface on which one lies upon which a zav will lie." This includes everything made to lie upon or ride upon, as we explained. Similarly, glass keilim made to lie upon contract impurity according to Rabbinic Law.
