Bekhorot 6
הכי אמר רבי יוחנן
Thus did R'Johanan say: Even if [the heathen's share in the firstling was only something constituting] a slight blemish,<span class="x" onmousemove="('comment',' Like the ear of the animal which is not a vital part, in which case the Israelite is exempt from the duty of the firstling.');"><sup>1</sup></span>
והדתנן
'A ewe which gave birth to a species of a goat or a goat which gave birth to a species of a ewe, is exempt from the duty of the firstling'.<span class="x" onmousemove="('comment',' For Scripture says: Or the firstling of a goat. Num. XVIII, 17. Both the firstling and the mother must belong to the same species and class i.e. a goat.');"><sup>3</sup></span>
אלא מום קבוע מאי קא משמע לן דכיון דאישתני הוה ליה מומא
means that] it is [like a firstling with] a permanent blemish, on account of which it is slaughtered.<span class="x" onmousemove="('comment',' I.e., outside the Temple. And eaten like any other firstling which possesses a blemish. It is, however, not suitable for sacrifice on the altar. This was R. Johanan's novel ruling emanating also from the House of Study, i.e., that a change in the animal renders it blemished.');"><sup>5</sup></span>
אלא לאו משום דאמרינן
And should you argue that [in the Mishnah just cited] the firstling has changed into a species [of animal] in which the sanctity of the firstling does not exist<span class="x" onmousemove="('comment',' That of a pig.');"><sup>8</sup></span>
כיון דאישתני הוה ליה מומא
but here the firstling has changed into a species [of animal] in which the sanctity of the firstling does exist,<span class="x" onmousemove="('comment',' And therefore this would be the novelty in the ruling of R. Johanan, that even in such an instance it is regarded as a blemish.');"><sup>9</sup></span>
מומין אלו בין קבועין בין עוברין פוסלין
Now, we may giant your argument as far as [the case of a firstling] with a small eye like a goose is concerned, this being a species<span class="x" onmousemove="('comment',' Birds being exempt from the law of the firstling.');"><sup>11</sup></span>
יתר עליהן אדם עיניו שתיהן גדולות שתיהן קטנות
in which the sanctity [of the firstling] does not exist.<span class="x" onmousemove="('comment',' There is need therefore for R. Johanan to inform us that even in this case it is a blemish since there is a change in the animal.');"><sup>12</sup></span>
(ויקרא כב, ד) איש איש מזרע אהרן דבעינן איש שוה בזרעו של אהרן אבל בהמה שתיהן גדולות שתיהן קטנות נמי לא הוי מומא
Must you not therefore admit that [the reason is] that we say since [the animal] is abnormal, it is regarded as a blemish?<span class="x" onmousemove="('comment',' What new thing consequently does R. Johanan tell us in his ruling that a change renders it blemished, since this may be inferred from the Mishnah?');"><sup>14</sup></span>
אי משום שינוי אפילו שתיהן גדולות שתיהן קטנות נמי
The reason is because it is a sarua'.<span class="x" onmousemove="('comment',' An animal whose one limb is larger than the other is called a sarua'. Therefore were it not stated in the House of Study that a change in the offspring e.g., where its wool resembles that of a goat, renders it blemished, I should not have been in a position to infer this from the Mishnah, as sarua' is a permanent blemish explicitly mentioned in the Scripture.');"><sup>15</sup></span>
התם אי מחמת בריותא יתירא תרווייהו בעי למיברא אי מחמת כחישותא יתירא תרווייהו בעי מיכחש
requiring 'man' among the seed of Aaron to be with normal [human features].<span class="x" onmousemove="('comment',' V. infra p. 289, n. 8.');"><sup>18</sup></span>
שותפות עובד כוכבים חייבת בבכורה
Then must you not admit that the reason [in the former case] is because of sarua'?<span class="x" onmousemove="('comment',' And it is not because of the change that an animal with one long and one short eye is regarded as blemished and therefore there is need for R. Johanan to inform us that elsewhere a change in the animal constitutes a blemish.');"><sup>19</sup></span>
דלמא אתי בהו לידי תקלה
And as for your question that the [same ruling] should apply to the case of an animal with two large and two small eyes, [the answer is that] there [in the latter instance] if [the change is] because of the animal's extra obesity, the two eyes need to be large, and if because of its unusual leanness, then both [eyes] have to be lean [small].<span class="x" onmousemove="('comment',' So that two large or small eyes constitute no change. Now since we can after all deduce from the Mishnah that a change renders the animal blemished, one can still raise the question, what is there novel in R. Johanan's ruling? (R. Gershom) .');"><sup>20</sup></span>
רב מרי מילתא הוא דעבד ואתי בה לידי תקלה:
Now, since he forbade the shearing and the working of the animals and gave them to the Priests, why did he give [a heathen] possession of the ears [of the firstlings? ]<span class="x" onmousemove="('comment',' For in this manner he carried out the prohibitions in connection with the firstling.');"><sup>25</sup></span>
<big><strong>מתני׳</strong></big> כהנים ולוים פטורין מק"ו
- [It was] lest he should be led to commit an offence.<span class="x" onmousemove="('comment',' In case he should shear and work the animal. And therefore he rendered himself exempt by transferring a part of the embryo to a heathen.');"><sup>26</sup></span>
אם פטרו את של ישראל במדבר דין הוא שיפטרו את של עצמן:
If so, why did the herd of R'Mari die?<span class="x" onmousemove="('comment',' Since his motives were good.');"><sup>27</sup></span> - Because he deprived them of their holiness.<span class="x" onmousemove="('comment',' By transferring a share of them to heathens.');"><sup>28</sup></span> But has not Rab Judah said: One is permitted to make a blemish in a firstling before it comes into the world?<span class="x" onmousemove="('comment',' As the sanctity of a firstling only begins after its birth.');"><sup>29</sup></span> - There, [in the latter case] he deprives the animal of the holiness of being sacrificed on the altar but he does not deprive it of the holiness [of belonging to] the Priests.<span class="x" onmousemove="('comment',' Like a firstling with a blemish whose shearing is forbidden and work with which is prohibited, still possessing a certain degree of holiness.');"><sup>30</sup></span> But in the former case, he even deprives it of the holiness [of belonging to] the Priests.<span class="x" onmousemove="('comment',' Although he actually observes all the prohibitions with reference to a blemished firstling, it is really rendered, owing to the share of the heathens, an unconsecrated animal.');"><sup>31</sup></span> Or, if you prefer, I may say that R'Mari B'Rahel knew how to make a valid transfer to a heathen.<span class="x" onmousemove="('comment',' To accept money from a heathen which is the valid method whereby a selling transaction is concluded with a gentile.');"><sup>32</sup></span> But we are afraid that another man may see this and go and do [likewise], thinking that R'Mari did nothing significant<span class="x" onmousemove="('comment',' Lit., 'did a mere word'.');"><sup>33</sup></span> [when transferring to a heathen].<span class="x" onmousemove="('comment',' By means of words only the transference was effected and no money was paid i.e., he simply informed the heathen that he had given him possession.');"><sup>34</sup></span> And thus he will be lead to commit an offence. <big><b>MISHNAH: </b></big>PRIESTS AND LEVITES ARE EXEMPT<span class="x" onmousemove="('comment',' Presumably from the first-born of an ass.');"><sup>35</sup></span> A FORTIORI: IF THEY EXEMPTED THE FIRST-BORN BELONGING TO THE ISRAELITES IN THE WILDERNESS,<span class="x" onmousemove="('comment',' This at present understood as meaning that since the Levites themselves exempted the asses of the Israelites in the wilderness, how much more should they exempt their own asses.');"><sup>36</sup></span> IT FOLLOWS A FORTIORI THAT THEY SHOULD EXEMPT THEIR OWN.
