Nazir 20A

ובית הלל סברי: משום אוירא גזרו עליה? לא, דכולי עלמא משום גושה גזרו עליה, ובית שמאי סברי בסתם נזירות קניסנא, ובית הלל סברי: כי קניסנא ⁠— בתחילת נזירות.

and Beit Hillel hold: They decreed with regard to its airspace, and it is a severe level of ritual impurity, so he must start his naziriteship from the beginning once he arrives in Eretz Yisrael. The Talmud rejects this possibility: No, it may be that everyone agrees that they decreed only with regard to its earth, and they disagree merely over the details of the penalty. Beit Shammai hold that we penalize him with an unspecified term of naziriteship, which is 30 days, and Beit Hillel hold that when we penalize, we require him to return to the beginning of his term of naziriteship, and he must observe the entire term of naziriteship afresh.

מעשה בהילני המלכה וכו׳. איבעיא להו: בשנטמאת, ואליבא דבית שמאי? או דלמא בשלא נטמאת, ואליבא דבית הלל?

§ The Mishnah taught: An incident occurred with regard to Queen Helene. A dilemma was raised before them: What is the meaning of R' Yehuda’s statement? Does he hold that the case was one where she became impure in Eretz Yisrael, but after 30 days, and not after 7 years, and R' Yehuda spoke in accordance with the opinion of Beit Shammai, who hold that she was required to observe only a further 30 days upon her arrival in Eretz Yisrael, and due to her becoming impure she had to observe again her original term of naziriteship, for a total of 14 years? Or perhaps the case is one where she did not become impure at the end of the 7 years in Eretz Yisrael, and he ruled in accordance with the opinion of Beit Hillel that she had to observe an additional 7 years upon her entry to Eretz Yisrael.
