Talmud for Nazir 6:2
וְחַיָּב עַל הַיַּיִן בִּפְנֵי עַצְמוֹ, וְעַל הָעֲנָבִים בִּפְנֵי עַצְמָן, וְעַל הַחַרְצַנִּים בִּפְנֵי עַצְמָן, וְעַל הַזַּגִּים בִּפְנֵי עַצְמָן. רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה אוֹמֵר, אֵינוֹ חַיָּב עַד שֶׁיֹּאכַל שְׁנֵי חַרְצַנִּים וְזַגָּן. אֵלּוּ הֵן חַרְצַנִּים וְאֵלּוּ הֵן זַגִּים, הַחַרְצַנִּים אֵלּוּ הַחִיצוֹנִים, הַזַּגִּים אֵלּוּ הַפְּנִימִים, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי יוֹסֵי אוֹמֵר, שֶׁלֹּא תִטְעֶה, כְּזוֹג שֶׁל בְּהֵמָה, הַחִיצוֹן זוֹג וְהַפְּנִימִי עִנְבָּל:
And he is liable for the wine in itself, for the grapes in themselves, for the chartzanim in themselves, and for the zagim in themselves. R. Elazar says: He is not liable until he eats two chartzanim (kernels) and their zag (husk), [it being written (Numbers 6:4): "from chartzanim until zag," the minimum of "chartzanim" being two, for which there is one zag. The halachah is not in accordance with R. Elazar b. Azaryah. But if one eats from chartzan and zag, he does not receive stripes until he eats an olive-size. Which are "charzanim" and which are "zagim"? The chartzanim are the outer (the husk); the zagim, the inner (the kernels). These are the words of R. Yehudah. R. Yossi says: Make no mistake. [R. Yossi gave a sign to prevent a mistake.] It is as the zug (bell) of a beast. The outer part is called "zug"; the inner part, "inbal" (the clapper).
Jerusalem Talmud Orlah
Anqoqlot190Neither the meaning nor the etymology of this word are known as will be clear from the Halakhah. In the opinion of Arukh, the word designates the edible young shoots of the vine; this follows the Gaonic commentary of R. Nathan Av Hayeshivah who reads קנוקלות, or the reading of Or Zarua קנוקנות, “hairline sinews” (Babli Ḥulin 92b). This explanation is incompatible with the Yerushalmi. In the opinion of S. Krauss, the word is an expansion of עקל to which compare Arabic עקּל “to produce grapes”. The text of Sifra [Qedošim Parasha 3(3)] את ענקוקלות והבוסר also shows that ענקוקלות are misdeveloped grapes., the grape skins, the grape seeds, and the afterwine made from them, pomegranate skins and their flowers191The remainder of the flower visible at the tip of the outer skin., nut shells, and seeds192Of any ‘orlah tree. are forbidden from ‘orlah, sacred groves, and for a nazir193Only the first four items.. They are permitted in the fourth year194Only fruits are forbidden unless redeemed.. Windfall195Of fully formed fruits. is forbidden for all of these.
Rebbi Yose said, one may plant an ‘orlah shoot but not an ‘orlah nut because the latter is a fruit. Also, one does not graft with spathe185Definition of Maimonides; Arabic טַלע. Arukh and Rashi, based on Gaonic sources, define as “dates that never ripen.” I. Löw (followed by S. Lieberman) takes it as the male flower which from an ‘orlah date palm may not be taken to hang into the branches of a female tree. of ‘orlah.
