Jerusalem Talmud Nedarim 6:7

משנה: הַנּוֹדֵר מִן הַתְּמָרִים מוּתָּר בִּדְבַשׁ תְּמָרִים. מִן הַסִּתְװָנִית מוּתָּר בְּחוֹמֶץ סִתְװָנִיּוֹת. רִבִּי יְהוּדָה בֶּן בְּתֵירָה אוֹמֵר כָּל־שֶׁשֵּׁם תּוֹלַדְתּוֹ קְרוּיָה עָלָיו וְנוֹדֵר מִמֶּנּוּ אָסוּר אַף בְּיוֹצֵא מִמֶּנּוּ. וַחֲכָמִים מַתִּירִין. MISHNAH: If somebody vows not to eat dates, he is permitted date honey; from winter grapes⁷⁶They are sour and can only be used for making vinegar., he is permitted winter grape vinegar. Rebbi Jehudah ben Bathyra says, if he vowed to forbid to himself anything which is called by the name of its derivative⁷⁷For example dates which in Deut. 8:8 are called “honey”. In the same verse, olives are referred to as “oil olives”., he also is forbidden the derivative, but the Sages permit it.

הלכה: הַנּוֹדֵר מִן הַתְּמָרִים כול׳. מַאי טַעֲמָא דְּרִבִּי יוֹסֵי. שֵׁם אָבִיו קָרוּי עָלָיו. מַאי טַעֲמָא דְּרִבִּי יְהוּדָה בֶּן בְּתֵירָה. שֵׁם בְּנוֹ קָרוּי עָלָיו. מִסְתַּבְּרָא רִבִּי יוּדָה בֶּן בְּתֵירָה יוֹדֵי לְרִבִּי יוֹסֵי. רִבִּי יוֹסֵי לֹא יוֹדֵי לְרִבִּי יוּדָה בֶּן בְּתֵירָה. רִבִּי יוּדָה בֶּן בְּתֵירָה יוֹדֵה לְרִבִּי יוֹסֵי. שֵׁם בְּנוֹ לֹא כָּל־שֶׁכֵּן שֵׁם אָבִיו. רִבִּי יוֹסֵי לֹא יוֹדֵה לְרִבִּי יְהוּדָה בֶּן בְּתֵירָה. לֹא אָמַר אֶלָּא שֵׁם אָבִיו. הָא שֵׁם בְּנוֹ לֹא. HALAKHAH: “If somebody vows not to eat dates,” etc. What is the reason of Rebbi Yose? The name of its father is called over it⁶⁰Since its name still contains the word “milk”.. What is the reason of Rebbi Jehudah ben Bathyra? The name of its descendant is called over it. It is reasonable that Rebbi Jehudah ben Bathyra should agree with Rebbi Yose but Rebbi Yose would not agree with Rebbi Jehudah ben Bathyra. Rebbi Jehudah ben Bathyra should agree with Rebbi Yose: The name of its descendant, so certainly also the name of its father. Rebbi Yose would not agree with Rebbi Jehudah ben Bathyra: He says only, the name of its father. This implies: not the name of its descendant.
