Mishnah 1א׳

הַשּׁוֹחֶה לִשְׁתּוֹת, הַמַּיִם הָעוֹלִים בְּפִיו וּבִשְׂפָמוֹ, בְּכִי יֻתַּן. בְּחָטְמוֹ וּבְרֹאשׁוֹ וּבִזְקָנוֹ, אֵינָן בְּכִי יֻתַּן. הַמְמַלֵּא בְּחָבִית, הַמַּיִם הָעוֹלִים אַחֲרֶיהָ, וּבַחֶבֶל שֶׁהוּא מְכֻנָּן עַל צַוָּארָהּ, וּבַחֶבֶל שֶׁהוּא לְצָרְכָּהּ, הֲרֵי זֶה בְכִי יֻתַּן. כַּמָּה הוּא צָרְכָּהּ. רַבִּי שִׁמְעוֹן בֶּן אֶלְעָזָר אוֹמֵר, טֶפַח. נְתָנָהּ תַּחַת הַצִּנּוֹר, אֵינָן בְּכִי יֻתַּן:

[If] one bends down to drink [from a river] the water that comes up in his mouth and on his mustache achieves BeKhi Yutan [a state where liquid put upon food makes it susceptible to impurity]. [The water that comes up] on his nose and on his head and in his beard does not achieve BeKhi Yutan. [If] one fills up a jar the water that comes up after it, and [the water] on the rope that is wound around its neck, and [the water] on the rope needed [for pulling it up] achieves BeKhi Yutan. How much [rope] is needed? Rabbi Shimon ben Elazar says: A hands-breadth. [If] one puts [the jar] under the gutter [of his roof] it does not achieve BeKhi Yutan.

Mishnah 2ב׳

מִי שֶׁיָּרְדוּ עָלָיו גְּשָׁמִים, אֲפִלּוּ אַב הַטֻּמְאָה, אֵינוֹ בְכִי יֻתַּן. וְאִם נִעֵר, בְּכִי יֻתַּן. עָמַד תַּחַת הַצִּנּוֹר לְהָקֵר אוֹ לִדּוֹחַ, בְּטָמֵא, טְמֵאִין. וּבְטָהוֹר, בְּכִי יֻתַּן:

[If] rain fell on an individual it does it not achieve BeKhi Yutan [if the water subsequently falls from him onto fruit] even if he is an Av HaTumah [a principal source of impurity]. But if he shook [the water off] that does achieve BeKhi Yutan. [If] one stood under the [roof] gutter to cool himself or to wash himself: [If] he was impure [the water] is impure; and [if] he was pure that achieves BeKhi Yutan.
