17 Our Mishnah says: WITH LIMBS [OF HULLIN] NO EXCHANGE CAN BE EFFECTED FOR [DEDICATED] EMBRYOS, NOR WITH EMBRYOS FOR LIMBS.<span class="x" onmousemove="('comment',' And the Mishnah goes on to say: NOR WITH WHOLE ANIMALS [OF HULLIN] FOR DEDICATED EMBRYOS.');"><sup>25</sup></span> Now it says that one has no power to exchange with them [the embryos],<span class="x" onmousemove="('comment',' For in connection with exchanging, Scripture says 'beast' but not an embryo.');"><sup>26</sup></span> but they [the embryos] can indeed become holy!<span class="x" onmousemove="('comment',' For if embryos cannot become holy, it is obvious that one has no power to exchange whole animals of holy with them, since they are hullin.');"><sup>27</sup></span> - He [R'Zera] replied to him: [Our Mishnah] is dealing with dedicated offspring which are already holy. If we are dealing with dedicated offspring, it is only in the inside of their mother that they do not effect exchange. We infer then that outside [their mother] they do effect exchange. But have we not learnt: One cannot effect exchange with the offspring of a dedicated animal?<span class="x" onmousemove="('comment',' Born after its mother's dedication, and the status of one exchanged with the young is not altered. We must then be dealing with a case where one consecrated directly an embryo, which is regarded as a first dedication. Hence we see that dedication has effect on an embryo, unlike the opinion of Bar Padda.');"><sup>28</sup></span> - [The Mishnah above] will represent the opinion of R'Judah who holds<span class="x" onmousemove="('comment',' Infra 11a, 12a, 14a.');"><sup>29</sup></span> that an animal's offspring effects exchange. If [th first part of our Mishnah above] is the opinion of R'Judah, it is only exchange which cannot be effected [with limbs],<span class="x" onmousemove="('comment',' Of hullin for whole dedicated animals, so that holiness should spread to the entire animal the limbs of which are being substituted.');"><sup>30</sup></span> but they [limbs] are indeed dedicated.<span class="x" onmousemove="('comment',' One can dedicate limbs, so that if one consecrated a limb of an animal, holiness spreads to the entire animal. For the first Tanna of the Mishnah must share this opinion, since R. Jose, his disputant in the Mishnah, retorts: IS IT NOT THE CASE WITH REFERENCE TO DEDICATIONS etc., thus implying that the first Tanna agrees with him that if one dedicated a limb the whole animal becomes holy, and it is R. Simeon who opposes R. Jose later in the Baraitha, saying that at the beginning the consecration of one limb makes the whole animal a burnt-offering, but the case of exchanging is different, as it has no effect on limbs.');"><sup>31</sup></span> But has not R'Judah stated: Limbs do not become holy?<span class="x" onmousemove="('comment',' Later in the Baraitha, R. Judah says that holiness does not spread to the whole animal where their limbs are dedicated.');"><sup>32</sup></span> - The case here<span class="x" onmousemove="('comment',' Where we deduce from the Mishnah that the entire animal becomes holy if one limb is dedicated.');"><sup>33</sup></span> is where he dedicated a limb the removal of which results in death.<span class="x" onmousemove="('comment',' Lit., 'on which the soul depends'; e.g., if he dedicated a foot from the joint upwards, the removal of which would render the animal trefah (v. Glos.) . Here, even R. Judah, the Baraitha says later, agrees that in such circumstances the whole animal becomes sacred.');"><sup>34</sup></span> He [R'Jeremiah] raised an objection to him [R'Zera]: One can dedicate limbs and embryos but one has no power to exchange [them].<span class="x" onmousemove="('comment',' Infra 15a. We therefore see that dedication has an effect upon embryos, unlike the opinion of Bar Padda.');"><sup>35</sup></span> - Here<span class="x" onmousemove="('comment',' In the case of the Mishnah just quoted.');"><sup>36</sup></span> also we are dealing with offspring of dedications. If the case is that offspring of dedications, why does the Baraitha say above: 'one can dedicate', for are they not already holy? -
