[If] the skylights are smaller than a handbreadth and tumah is in the house, whatev-er is directly opposite the skylights remains tahor. [If] the tumah is directly opposite the skylights, the house remains tahor.   [If] tumah is in the house and an item, either susceptible to tumah or not, is placed over either the upper or the lower [skylight], only the lower story becomes tamei. [If] the tumah is directly opposite the skylights and an item susceptible to tu-mah is placed over either the upper or the lower [skylight], everything becomes tamei. [If] an item not susceptible to tumah is placed over either the upper or the lower [skylight], only the lower story becomes tamei.

[If] there is a skylight in [the roof of] a house, and a pot is placed beneath [the sky-light] so that if [the pot] were raised its edges would not touch the [roof surrounding the] skylight, and there is tumah below, inside, or above [the pot], the tumah pene-trates upward and downward. [If the pot] is one handbreadth above the ground and there is tumah below it or inside the house, [the area] below [the pot] and [the] inside [of] the house be-come tamei, but whatever is inside or above [the pot] remains tahor. [If the tumah] is inside or above [the pot], everything becomes tamei.
