סְתָם נְזִירוּת שְׁלֹשִׁים יוֹם. כֵּיצַד. מִי שֶׁאָמַר הֲרֵינִי נָזִיר אֵין פָּחוֹת מִשְּׁלֹשִׁים יוֹם. וַאֲפִלּוּ אָמַר הֲרֵינִי נָזִיר נְזִירוּת גְּדוֹלָה עַד מְאֹד הַרְבֵּה הֲרֵי זֶה נָזִיר שְׁלֹשִׁים יוֹם. שֶׁהֲרֵי לֹא פֵּרֵשׁ זְמַן:
If a specification is not made the term for a nazirite vow is 30 days. What is implied? If a person said: "I am a nazirite," [he must uphold his vow] for no less than 30 days. Even if he said: "I will be a nazirite for an excessively long and protracted time," he must uphold the nazirite vows for [only] 30 days, for he did not specify a time.
