Reference for Yoma 161:20
לאיי אפנויי מופנה חמשה קראי כתיבי במלאכה חד לאזהרה דיממא וחד לאזהרה דליליא וחד לעונש דיממא וחד לעונש דליליא וחד לאפנויי למגמר עינוי ממלאכה בין דיממא בין דליליא
But against this it may be objected:<span class="x" onmousemove="('comment',' The comparison is superficial, because in spite of similarity of expression, basic difference of prevailing conditions render the comparison unjustified, and but for an explicit statement of penalty in the case of 'labour' one would not be able to derive it from 'affliction'.');"><sup>20</sup></span> The specific condition with affliction [which attaches a penalty to it] lies in the fact that no exception against the general rule was made here; but would you apply [the same] to the performance of labour seeing that in its case exceptions from the general rule were made?<span class="x" onmousemove="('comment',' None is exempted from the affliction, whereas as regards labour the priests in the Sanctuary were permitted to perform all work in connection with the ceremonial of the Day of Atonement.');"><sup>21</sup></span>
