Reference for Pesachim 154:11
ובמנחות לא אמר והתנן נטמאו שיריה אבדו שיריה כמדת רבי אליעזר כשירה כמדת רבי יהושע פסולה
- You may even say [that it agrees with] R'Joshua, but R'Joshua holds: The headplate propitiates for those that ascend.<span class="x" onmousemove="('comment',' The altar, sc. the emurim; i.e., providing that as much as an olive of the emurim ascends the altar, the headplate propitiates for its defilement, and the blood too can be sprinkled.');"><sup>14</sup></span> That is well of sacrifices, where there are objects which ascend [sc. emurim]; but what can be said of the 'omer and the two loaves, where there are no objects to ascend [the altar]? - I will tell you: R'Joshua too said that we require both only in the case of sacrifices; [but] he did not say [it] in the case of meal-offerings.
