And was it not taught: Rabbi said, Then thou shalt kill [of thy herd and of thy flock]. as I have commanded thee.<span class="x" onmousemove="('comment',' Deut. XII, 21.');"><sup>10</sup></span> This teaches that Moses received commandments concerning the gullet, and the windpipe, and concerning the larger part of one [organ] in the case of a fowl, and the larger part of two in the case of cattle?<span class="x" onmousemove="('comment',' The windpipe and the gullet, one in the case of fowl, both in the case of cattle, must be cut according to the ritual. There is no commandment anywhere in the Pentateuch as to the details of ritual slaughtering of animals or birds, called shechitah. Hence 'as I have commanded thee' must needs refer to another source of law: the unwritten or oral one.');"><sup>11</sup></span>
