לָזוֹ אַחַת, לָזוֹ שְׁתַּיִם, לָזוֹ שָׁלשׁ, לָזוֹ אַרְבַּע, לָזוֹ חָמֵשׁ, לָזוֹ שֵׁשׁ, לָזוֹ שֶׁבַע. פָּרַח מִן הָרִאשׁוֹנָה לַשְּׁנִיָּה, לַשְּׁלִישִׁית, לָרְבִיעִית, לַחֲמִישִׁית, לַשִּׁשִּׁית, לַשְּׁבִיעִית, חָזַר, פּוֹסֵל אֶחָד בַּהֲלִיכָתוֹ וְאֶחָד בַּחֲזִירָתוֹ. הָרִאשׁוֹנָה וְהַשְּׁנִיָּה אֵין לָהֶם כְּלוּם, הַשְּׁלִישִׁית יֶשׁ לָהּ אַחַת, הָרְבִיעִית יֶשׁ לָהּ שְׁתַּיִם, הַחֲמִישִׁית יֶשׁ לָהּ שָׁלשׁ, הַשִּׁשִּׁית יֶשׁ לָהּ אַרְבַּע, הַשְּׁבִיעִית יֶשׁ לָהּ שֵׁשׁ. פָּרַח וְחָזַר, פּוֹסֵל אֶחָד בַּהֲלִיכָתוֹ וְאֶחָד בַּחֲזִירָתוֹ. הַשְּׁלִישִׁית וְהָרְבִיעִית אֵין לָהֶם כְּלוּם, הַחֲמִישִׁית יֶשׁ לָהּ אַחַת, הַשִּׁשִּׁית יֶשׁ לָהּ שְׁתַּיִם, הַשְּׁבִיעִית יֶשׁ לָהּ חָמֵשׁ. פָּרַח וְחָזַר, פּוֹסֵל אֶחָד בַּהֲלִיכָתוֹ וְאֶחָד בַּחֲזִירָתוֹ, הַחֲמִישִׁית וְהַשִּׁשִּׁית אֵין לָהֶם כְּלוּם, הַשְּׁבִיעִית יֶשׁ לָהּ אַרְבַּע. וְיֵשׁ אוֹמְרִים, הַשְּׁבִיעִית לֹא הִפְסִידָה כְלוּם. וְאִם פָּרַח מִבֵּין הַמֵּתוֹת לְכֻלָּם, הֲרֵי כֻלָּם יָמוּתוּ:

If this one [woman] has one [pair of birds], and this one [woman] has two [pairs of birds], this one has three [pairs], this one has four [pairs], this one five [pairs], this one six [pairs] and this one seven [pairs], and one bird flew from the first [group] to the second ]group] and one [flew from the second group] into the third [group], and one [flew from the third group]into the fourth [group], and one [flew from the fourth group] into the fifth [group], and one [flew from the fifth group] into the sixth [group], and one [flew from the sixth group] into the seventh [group], and then one returned [to its previous group], it invalidates one pair [for each woman] when it leaves and one pair [for each woman] upon its return. [Therefore], the first and second [groups of women] have no valid birds left, the third [group] has one [valid pair], the fourth [group] has two [valid pairs], the fifth [group] has three[valid pairs], the sixth [group] has four [valid pairs], and the seventh [group] has six [valid pairs]. If it [a bird] flew back and fourth ]through the remaining sets of birds], it invalidates one set when it leaves and one set upon its return. [Therefore] the third and fourth [group] have nothing [no valid pairs], the fifth [group] has one [valid pair], the sixth [group] has two [valid pairs] and the seventh [group] has five. If a bird flew back and forth, it invalidates one pair when it leaves and one upon its return. The fifth and sixth [group] have no valid birds and the seventh [group] has four. Others say the seventh woman did not lose anything and if a bird that is left to die flew into their group they all must be left to die.

Mishnah 4ד׳

קֵן סְתוּמָה וְקֵן מְפֹרֶשֶׁת, פָּרַח מִן הַסְּתוּמָה לַמְפֹרֶשֶׁת, יִקַּח זוּג לַשֵּׁנִי. חָזַר, אוֹ שֶׁפָּרַח מִן הַמְפֹרֶשֶׁת רִאשׁוֹן, הֲרֵי כֻלָּן יָמוּתוּ:

An unspecified pair of birds [one of which is a burnt-offering and the other is a sin offering] and a pair of specified birds, if a bird from the unspecified birds flew into the pair of specified birds he [the owner] must bring a second bird for the second one [remaining unspecified bird]. Or if a bird flew from the original specified birds [to the unspecified birds], they must all be left to die.
