A drawer of a cabinet contains a [cubic] handbreadth of empty space and has an opening smaller than a [square] handbreadth. [If there is] tumah inside [the drawer], the house becomes tamei. [If] there is tumah inside the house, whatever is inside [the drawer] remains tahor, because it is the way of the tumah to exit, but it is not the way [of the tumah] to enter. R’ Yose rules [the house] tahor, because one can remove [the tumah] in halves, or burn it in its place.
