[If] a cabinet is standing in the open air, and has tumah inside it, [the] utensils inside its sides remain tahor. [If] tumah is inside its sides, the utensils inside [the cabinet] remain tahor. R’ Yose says: Half and half. [If the cabinet] is standing inside a house, [and] tumah is inside [the cabinet], the house becomes tamei. [If] tumah is inside the house, whatever is inside [the cab-inet] remains tahor, because it is the way of the tumah to exit, but it is not the way [of the tumah] to enter. [In a case where] there are utensils between [the cabinet] and either the ground, the wall, or the ceiling beams — if there is a space of one handbreadth, they are tamei; but if not, they are tahor. [If] tumah is there, the house becomes tamei.
