Meir nevertheless does not regard it as levitically clean.');"><sup>2</sup></span>
וסבר ר"מ ספיקא לחומרא והתנן טמא שירד לטבול ספק טבל ספק לא טבל ואפילו טבל ספק טבל בארבעים סאה ספק לא טבל בארבעים סאה וכן שני מקוואות באחת יש בה ארבעים סאה ובאחת אין בה ארבעים סאה וטבל באחת מהן ואינו יודע באיזה מהן טבל ספיקו טמא
But is R'Meir of the opinion that in a doubtful case<span class="x" onmousemove="('comment',' As is the case in our Mishnah where it is uncertain whether the terumah became unclean before or after twilight.');"><sup>3</sup></span> the more restrictive course is to be followed?<span class="x" onmousemove="('comment',' Since he did not regard the terumah as having become unclean after twilight.');"><sup>4</sup></span>

and, similarly, if he performed his immersion in one of two ritual baths, one of which contained forty se'ah [of water] and the other contained less,<span class="x" onmousemove="('comment',' Cf. previous note.');"><sup>9</sup></span> and he does not know in which one he performed his immersion he, being in a state of doubt, is unclean.<span class="x" onmousemove="('comment',' Mik.

This applies only to a major uncleanness<span class="x" onmousemove="('comment',' Sc. one that is Pentateuchal (Rashi) .');"><sup>11</sup></span> but in the case of a minor uncleanness<span class="x" onmousemove="('comment',' One that is only Rabbinically so.');"><sup>12</sup></span>

and he then went down to perform immersion and it is doubtful whether he did or did not perform it, and even if he did perform it there is doubt whether the immersion was performed in forty se'ah [of water] or less, and, similarly, if he performed the immersion in one of two ritual baths one of which contained forty se'ah, [of water] and the other contained less, and he does not know in which of the two he performed his immersion he, being in a state of doubt, is clean; so R'Meir;<span class="x" onmousemove="('comment',' This is the reading of Bomb. ed.

Meir.');"><sup>15</sup></span> and R'Jose declared him to be unclean?<span class="x" onmousemove="('comment',' Mik. II, 2; from which it follows that in a doubtful case It.

לא קשיא הא דידיה הא דרביה דיקא נמי דקתני בזו אמר רבי דוסתאי בר ינאי משום רבי מאיר שמעתי שמקדרין בהרים ש"מ
- R'Meir is of the opinion [that the laws of the Sabbath] limits<span class="x" onmousemove="('comment',' Of which our Mishnah speaks.');"><sup>17</sup></span> are Pentateuchal.<span class="x" onmousemove="('comment',' In a Pentateuchally doubtful prohibition the more restrictive ruling is followed.

ורמי דאורייתא אדאורייתא לרבי מאיר
But does R'Meir uphold the view that [the laws of Sabbath] limits are Pentateuchal? Have we not in fact learnt: If he is unable to span it<span class="x" onmousemove="('comment',' Lit., 'to cause it to be swallowed'. This term (v. infra 58a, f) is applied to a wall, a hill or similar elevation or depression whose horizontal distance can be measured by a rope of the length of fifty cubits held at either end by one man. If the horizontal distance is more than fifty cubits and a rope of the length mentioned cannot span it, a different method of measuring, described anon, must be adopted.');"><sup>19</sup></span>
דתנן נגע באחד בלילה ואינו יודע אם חי אם מת ולמחר השכים ומצאו מת רבי מאיר מטהר וחכמים מטמאין שכל הטמאות כשעת מציאתן
- in connection with this R'Dostai B'Jannai stated in the name of R'Meir: 'I have heard that hills are [treated as though they were] pierced' ,<span class="x" onmousemove="('comment',' Infra 8a. Sc. the measuring of a hill or any elevation or depression in the way of the surveyors (cf. previous note) is carried out by a method which produces its horizontal distance, the measuring rope, manipulated in a certain manner (described infra 58b) being regarded as piercing it in a straight line and emerging on its other side.');"><sup>20</sup></span> Now if the idea could be entertained [that the laws of the Sabbath] limits are Pentateuchal [the difficulty would arise:] Is [the method of] piercing allowed [in such a case] seeing that R'Nahman has in fact stated in the name of Rabbah B'Abbuha [that the method of] piercing must not [be adopted] in the case of [the measurements around] the cities of refuge,<span class="x" onmousemove="('comment',' Cf. Num. XXXV, 11ff. Not only the cities themselves but also a limited area within a prescribed distance from each city affords the privilege of protection (cf. Mak. 11b) .');"><sup>21</sup></span>

While such latitude in favour of the persons concerned was allowed in the case of Rabbinical ordinances, it was not allowed in that of Pentateuchal ones in connection with which the stricter method, which takes count of the slopes also, must be adopted. Now, since R. Meir allows the method of 'piercing' in the case of Sabbath limits, how could it be maintained that in his view these laws are Pentateuchal?');"><sup>23</sup></span>
רבה ורב יוסף דאמרי תרוייהו הכא בשתי כיתי עדים עסקינן אחת אומרת מבעוד יום נטמאה ואחת אומרת משחשיכה
- This is no difficulty; one ruling was<span class="x" onmousemove="('comment',' Lit., 'that', the ruling of R. Meir in our Mishnah which implies that in his opinion the laws of the Sabbath limits are Pentateuchal since the more restrictive course is followed in cases of doubt.');"><sup>24</sup></span> his own while the other<span class="x" onmousemove="('comment',' That the method of 'piercing' may be adopted in determining the Sabbath limits.');"><sup>25</sup></span> was his master's.<span class="x" onmousemove="('comment',' Referring to R. Meir himself.');"><sup>26</sup></span> A careful examination [of the wording] also [leads to this conclusion]. For it was taught: In connection with this R'Dostai B'Jannai stated in the name of R'Meir, 'I have heard that hills are [treated as though they were] pierced'.<span class="x" onmousemove="('comment',' Emphasis on 'heard', sc. but he himself (R. Meir) does not share that view.');"><sup>27</sup></span> This proves it. A contradiction, however, was pointed out between two rulings of R'Meir in respect of Pentateuchal laws.<span class="x" onmousemove="('comment',' Lit., 'of the Law on the Law according to R. Meir'.');"><sup>28</sup></span> For have we not learnt: If a man who touched a body at night was unaware whether it was alive or dead but when rising on the following morning he found it to be dead, R'Meir regards him as clean;<span class="x" onmousemove="('comment',' Because, as it is obvious that the body was alive until the moment of death approached, it is also presumed to have been alive at the time it was touched.');"><sup>29</sup></span> and the Sages regard him as unclean because [questions in respect of] all unclean objects [are determined] in accordance with their condition at the time they were discovered?<span class="x" onmousemove="('comment',' Toh. V, 7. As at the time of discovery the body was dead it must also be presumed to have been dead when it was touched. R. Meir, at any rate, adopts here, though the laws of uncleanness are Pentateuchal, the lenient view. Why then did he adopt the stricter view in our Mishnah? As the body here is presumed to have been alive at the time it was touched so should the terumah (in the Mishnah) have been presumed to have been clean at the time the Sabbath began.');"><sup>30</sup></span> - R'Jeremiah replied: Our Mishnah [refers to terumah] on which a [dead] creeping thing lay throughout the twilight.<span class="x" onmousemove="('comment',' Of the Sabbath eve. The uncleanness of the terumah must consequently have set in prior to the commencement of the Sabbath.');"><sup>31</sup></span> But if so, would R'Jose have ruled: AN 'ERUB [WHOSE VALIDITY IS] IN DOUBT IS EFFECTIVE?<span class="x" onmousemove="('comment',' Obviously not, since this is not a case of doubt but one of certainty where (v. our Mishnah) all agree that the 'erub is ineffective.');"><sup>32</sup></span> - Both Rabbah and R'Joseph replied: We are here dealing with two groups of witnesses, one of which testifies that the uncleanness occurred while it was yet day, while the other testifies [that it occurred] after dusk.<span class="x" onmousemove="('comment',' In the opinion of R. Jose the two groups of witnesses cancel each other out and the terumah is, therefore, presumed to have been, at the time the Sabbath began, in its former state of presumptive cleanness. R. Meir, however, maintains that, since the presumptive cleanness of the terumah has been denied by one group of witnesses, its cleanness becomes a matter of doubt when, being a Pentateuchal law, the more restrictive course must be followed. In the case of a body (cited from Toh. V, 7) its presumptive life at the time it was touched has not been contradicted by any witnesses.');"><sup>33</sup></span> [
