הַזָּב וְהַטָּהוֹר שֶׁיָּשְׁבוּ בִסְפִינָה אוֹ בְאַסְדָּא אוֹ שֶׁרָכְבוּ עַל גַּבֵּי בְהֵמָה, אַף עַל פִּי שֶׁאֵין בִּגְדֵיהֶם נוֹגְעִים, הֲרֵי אֵלּוּ טְמֵאִים מִדְרָס. יָשְׁבוּ עַל הַנֶּסֶר, עַל הַסַּפְסָל, עַל הַגָּשִׁישׁ שֶׁל מִטָּה וְעַל הָאַכְלוֹנָס, בִּזְמַן שֶׁהֵן מַחְגִּירִין, עָלוּ בְאִילָן שֶׁכֹּחוֹ רַע, בְּסוֹכָה שֶׁכֹּחָהּ רַע, בְּאִילָן יָפֶה, בְּסֻלָּם מִצְרִי בִּזְמַן שֶׁאֵינוֹ קָבוּעַ בְּמַסְמֵר, עַל הַכֶּבֶשׁ וְעַל הַקּוֹרָה וְעַל הַדֶּלֶת בִּזְמַן שֶׁאֵין עֲשׂוּיִין בְּטִיט, טְמֵאִים. רַבִּי יְהוּדָה מְטַהֵר: A zav and a clean person who sat together in a boat, or on a raft, or rode together on a beast, even though their garments did not touch, behold they are impure through midras. If they sat together on a plank, on a bench or on a bed-frame, or on a beam, when these were not fixed tightly, [Or] if they had both climbed a weak tree, or [were swaying] on a weak branch of a strong tree; Or if they were both [climbing] on an Egyptian ladder which was not secured by a nail; Or if they sat together on a bridge, rafter or door, not secured by clay, they are unclean. Rabbi Judah says that they are clean.
מְגִיפִין אוֹ פוֹתְחִין. וַחֲכָמִים אוֹמְרִים, עַד שֶׁיְּהֵא זֶה מֵגִיף וְזֶה פוֹתֵחַ. מַעֲלִין זֶה אֶת זֶה מִן הַבּוֹר. רַבִּי יְהוּדָה אוֹמֵר, עַד שֶׁיְּהֵא הַטָּהוֹר מַעֲלֶה אֶת הַטָּמֵא. מַפְשִׁילִין בַּחֲבָלִין. וַחֲכָמִים אוֹמְרִים, עַד שֶׁיִּהְיֶה זֶה מוֹשֵׁךְ הֵילֵךְ וְזֶה מוֹשֵׁךְ הֵילֵךְ. אוֹרְגִים, בֵּין בְּעוֹמְדִין בֵּין בְּיוֹשְׁבִין אוֹ טוֹחֲנִין. רַבִּי שִׁמְעוֹן מְטַהֵר בְּכֻלָּן, חוּץ מִן הַטּוֹחֲנִין בְּרֵחַיִם שֶׁל יָד. פּוֹרְקִין מִן הַחֲמוֹר אוֹ טוֹעֲנִין, בִּזְמַן שֶׁמַּשָּׂאָם כָּבֵד, טְמֵאִין. בִּזְמַן שֶׁמַּשָׂאָם קַל, טְהוֹרִין. וְכֻלָּן טְהוֹרִין לִבְנֵי הַכְּנֶסֶת וּטְמֵאִין לַתְּרוּמָה: If they were both closing or opening [a door], [the clean person and his clothes are unclean]. But the sages say: [he is not unclean] unless one was shutting and the other opening [it]. If one was lifting the other out of a pit [the clean person and his clothes are unclean]. Rabbi Judah says: only if the clean person was pulling out the unclean one. If they were twisting ropes together [the clean person and his clothes are unclean]. But the sages say: unless the one pulled one way and the other pulled the other way. If they were both weaving together, whether they were standing or sitting, or grinding wheat, [the clean person and his clothes are unclean]. Rabbi Shimon says [the clean person] in every case is pure, except where they [both] were grinding with a hand-mill. If they [both] were unloading or loading a donkey, they are unclean if the load was heavy, but clean if the load was light. In all cases, however, they are clean for members of the synagogue, but are unclean for terumah.
הַזָּב וְהַטָּהוֹר שֶׁיָּשְׁבוּ בִסְפִינָה גְדוֹלָה, אֵיזוֹ הִיא סְפִינָה גְדוֹלָה. רַבִּי יְהוּדָה אוֹמֵר, כֹּל שֶׁאֵינָהּ יְכוֹלָה לְהָמִיט בָּאָדָם. יָשְׁבוּ עַל הַנֶּסֶר, עַל הַסַּפְסָל, עַל הַגָּשִׁישׁ שֶׁל מִטָּה וְעַל הָאַכְלוֹנָס בִּזְמַן שֶׁאֵינָן מַחְגִּירִין, עָלוּ בְאִילָן שֶׁכֹּחוֹ יָפֶה, בְּסוֹכָה שֶׁכֹּחָהּ יָפֶה, וּבְסֻלָּם צוֹרִי אוֹ מִצְרִי בִּזְמַן שֶׁהוּא קָבוּעַ בְּמַסְמֵר, עַל הַכֶּבֶשׁ, עַל הַקּוֹרָה וְעַל הַדֶּלֶת בִּזְמַן שֶׁהֵן עֲשׂוּיִין בְּטִיט אֲפִלּוּ מִצַּד אֶחָד, טְהוֹרִין. הַטָּהוֹר מַכֶּה אֶת הַטָּמֵא, טָהוֹר. הַטָּמֵא מַכֶּה אֶת הַטָּהוֹר, טָמֵא, שֶׁאִם יִמָּשֵׁךְ הַטָּהוֹר, הֲרֵי הַטָּמֵא נוֹפֵל: If the zav and the clean person sat together in a large boat: (what is considered a large boat? Rabbi Judah said: one that does not sway with a man's weight), or if they sat on a plank, bench, bed-frame, or beam when these were firmly secured; Or if they both climbed a strong tree, a firm branch, or a Tyrian ladder, or an Egyptian ladder fixed by a nail; Or if they sat on a bridge, rafter or door, when these were fastened with clay, even if only at one end, they remain clean. If the clean one struck the unclean one, he still remains clean. But if the unclean one struck the clean one, he is impure; for [in that case] if the clean one drew back, the unclean one would have fallen.
