Ohalos9: 8
הָיְתָה גָבוֹהַּ מִן הָאָרֶץ טֶפַח: טֻמְאָה תַחְתֶּיהָ אוֹ בַבַּיִת אוֹ בְתוֹכָהּ, הַכֹּל טָמֵא, אֶלָּא גַבָּהּ. עַל גַּבָּהּ, כְּנֶגְדּוֹ עַד הָרָקִיעַ טָמֵא.
[If the hive] is a handbreadth above the ground, [and] there is tumah below it, in the house, or inside [the hive], everything becomes tamei except for what is above [the hive]. [If the tumah] is above [the hive], [utensils] directly above [the tumah] up to the sky become tamei.
