כב מנא הני מילי דתנו רבנן (ויקרא יח) אך את זה לא תאכלו ממעלי הגרה וממפריסי הפרסה יש לך שהוא מעלה גרה ומפריס פרסה ואי אתה אוכלו ואיזה זה טהור שנולד מן הטמא או אינו אלא טמא הנולד מן הטהור ומאי ממעלי הגרה וממפריסי הפרסה
22 But here [in the case where an ass gave birth to a species of horse], since in both instances, they have no horns and the hoofs of both are closed, I might have said that the offspring [a species of horse] was merely a red ass.<span class="x" onmousemove="('comment',' And not a horse at all. An ordinary horse is red in color and an ordinary ass is black. Consequently, if the horse had some features like its parents, we ought perhaps to regard it as a kind of red ass, thus making it liable to the law of the firstling.');"><sup>24</sup></span> We are therefore informed [that this is not so].<span class="x" onmousemove="('comment',' Since a horse's color is generally red we regard it as a species of a horse and not as a freak ass.
