Nazir1: 7
”הֲרֵינִי נָזִיר כְּמִנְיַן יְמוֹת הַחַמָּה” — מוֹנֶה נְזִירוּת כְּמִנְיַן יְמוֹת הַחַמָּה. אָמַר רַבִּי יְהוּדָה: מַעֲשֶׂה הָיָה, כֵּיוָן שֶׁהִשְׁלִים — מֵת.
[If one says:] “I am a nazir like the number of days of the solar [year],” he counts [terms of] nezirus like the number of days of the solar [year]. R’ Yehudah said: There was an incident, and when he concluded, he died.
