רַבִּי יְהוּדָה אוֹמֵר: אַף הֵן צְרִיכִין לְקַבֵּל דִּבְרֵי חֲבֵרוּת לְכַתְּחִלָּה. וְכֵן הָיָה רַבִּי שִׁמְעוֹן בֶּן אֶלְעָזָר אוֹמֵר: מַעֲשֶׂה בְּאִשָּׁה אַחַת שֶׁנִּשֵּׂאת לְחָבֵר, וְהָיְתָה קוֹשֶׁרֶת לוֹ תְּפִילִּין עַל יָדוֹ, נִשֵּׂאת לְמוֹכֵס, וְהָיְתָה קוֹשֶׁרֶת לוֹ קִשְׁרֵי מוֹכֵס עַל יָדוֹ. אָמַר רַב: חבי״ת אָסוּר בְּחוֹתָם אֶחָד, חמפ״ג מוּתָּר בְּחוֹתָם אֶחָד. חָלָב, בָּשָׂר, יַיִן, תְּכֵלֶת. אֲסוּרִין בְּחוֹתָם אֶחָד. חִילְתִּית, מוּרְיָיס, פַּת, גְּבִינָה — מוּתָּרִין בְּחוֹתָם אֶחָד....
Rabbi Yehuda says: They too must accept upon themselves the commitment to observe the matters associated with ḥaver status ab initio. And similarly, Rabbi Shimon ben Elazar would illustrate this point and say: There was an incident involving a certain woman who married a ḥaver and would tie for him phylacteries on his hand, and she later married a tax collector and would tie for him tax-seals on his hand, which shows that her new husband had a great influence on her level of piety. § Rav says: The substances represented by the acronym ḥet, beit, yod, tav are prohibited if they were deposited with a gentile while they were sealed with only one seal. Those represented by the acronym ḥet, mem, peh, gimmel are permitted if they were deposited with a gentile while they were sealed with one seal. The Gemara elaborates: Milk [ḥalav], meat [basar], wine [yayin], and sky-blue dye [tekhelet] are all prohibited when they are found with only one seal; ḥiltit, fish stew [morayes], bread [pat], and cheese [gevina] are all permitted when they are found with one seal.
