Keilim 24:17-25:1
Keilim 24:17
There are three kinds of basket: if a worn out basket is fastened to an intact basket (to reinforce it), everything is based on the intact basket. If a small basket is fastened to a large basket, everything is based on the large basket. If the baskets are of the same size and condition, then everything is based on the inner basket. Rabbi Shimon says that if the (ritually impure) pan of a scale was used to patch the bottom of a (ritually pure) kettle on the inside, then the kettle is rendered impure; if on the outside, then the kettle remains pure. If the kettle was patched on the side, then whether it was patched on the inside or the outside, it remains pure.
Keilim 25:1
All vessels – such as cushions, mattresses, sacks and packing cases – have different rules for their outsides and their insides; this is the opinion of Rabbi Yehuda. Rabbi Meir says that a utensil that has loops (such as for hanging) has different rules for its outside and its inside but one that doesn’t have loops doesn’t have different rules for its outside and inside. A table and a sideboard have different rules for their outsides and their insides; this is the opinion of Rabbi Yehuda. Rabbi Meir says that they don’t have different rules for their outsides and their insides. The same dispute applies to a slab without a rim.
