Reference for Yoma 4:5
לכפר אלו מעשה יום הכפורים ואימא כפרה דקרבנות
But what does it matter? Did not the school of R'Ishmael teach that [in the verse], The priest shall return or the priest shall come in,<span class="x" onmousemove="('comment',' Ibid. Xlv, 39.');"><sup>13</sup></span> 'returning' and 'coming in' mean one and the same thing?<span class="x" onmousemove="('comment',' For the purposes of inference v. Hor., Sonc. ed., p. 57, n. 11. So that such literalness as the insistence on differentiation between ziwwah and zawwotho is not justified.');"><sup>14</sup></span> - These words [of the school of R'Ishmael] apply only when there is no identical word,<span class="x" onmousemove="('comment',' From the congruity of which an analogy may be inferred.');"><sup>15</sup></span>
