פרה ט׳Parah 9

Mishnah 1א׳

צְלוֹחִית שֶׁנָּפַל לְתוֹכָהּ מַיִם כָּל שֶׁהֵן, רַבִּי אֱלִיעֶזֶר אוֹמֵר, יַזֶּה שְׁתֵּי הַזָּיוֹת. וַחֲכָמִים פּוֹסְלִין. יָרַד לְתוֹכָהּ טַל, רַבִּי אֱלִיעֶזֶר אוֹמֵר, יַנִּיחֶנָּה בַחַמָּה וְהַטַּל עוֹלֶה. וַחֲכָמִים פּוֹסְלִין. נָפַל לְתוֹכָהּ מַשְׁקִין וּמֵי פֵרוֹת, יְעָרֶה וְצָרִיךְ לְנַגֵּב. דְּיוֹ, קוֹמוֹס, וְקַנְקַנְתּוֹם, וְכָל דָּבָר שֶׁהוּא רוֹשֵׁם, יְעָרֶה וְאֵינוֹ צָרִיךְ לְנַגֵּב:

A flask [of water which has already been mixed with ashes and sanctified] into which an[y] amount of water fell, Rabbi Eliezer says: One should sprinkle two sprinklings [instead of one, on a ritually impure individual in order to purify him]; and the Sages invalidate [the waters]. If dew fell into it, Rabbi Eliezer says: One should leave it in the sun and the dew will rise [i.e. evaporate]; and the Sages invalidate [the water]. If liquids or fruit juices fell into it, one should pour it out [because it has been invalidated], and drying [of the vessel before reuse] is required. If ink, or coloured charcoal, or coloured water, or anything which leaves a mark [fell into the water], one should pour it out [because it has been invalidated] and drying [the vessel before reuse] is not required.

Mishnah 2ב׳

נָפַל לְתוֹכָהּ שְׁקָצִים וּרְמָשִׂים וְנִתְבַּקְּעוּ, אוֹ שֶׁנִּשְׁתַּנּוּ מַרְאֵיהֶם, פְּסוּלִין. חִפּוּשִׁית, בֵּין כָּךְ וּבֵין כָּךְ פּוֹסֶלֶת, מִפְּנֵי שֶׁהִיא כִשְׁפוֹפֶרֶת. רַבִּי שִׁמְעוֹן וְרַבִּי אֱלִיעֶזֶר בֶּן יַעֲקֹב אוֹמְרִים, הַדִּירָה וְהַכִּנָּה שֶׁבַּתְּבוּאָה כְּשֵׁרִים, מִפְּנֵי שֶׁאֵין בָּהֶם לֵחָה:

If insects or crawling creatures fell into it [the water] and they split open [and released liquid into the water], or if their [the waters'] appearance was changed [because of the insects], they [the waters] are invalid. If [the insect was] a chipushit [a type of black worm], either way [even if no change occurred] it invalidates [the water] because it is like a tube [and invalidates the water like any tube or open vessel containing liquid]. Rabbi Shimon and Rabbi Eliezer ben Ya'akov say: If [what fell in the water was] a dira or kina of the produce [types of insect], they [the waters] are valid because those [insects] contain no liquid.
