Reference for Menachot 18:20

ואימא אדרבה מה כאן שמאלית אף בעלמא נמי שמאלית ארבעה שמאלית כתיבי תרי בעני ותרי בעשיר

R'Jannai said, It is written, of the meal-offering,<span class="x" onmousemove="('comment',' Lev. II. 3.');">²⁷</span> that is, the meal-offering which was once whole.<span class="x" onmousemove="('comment',' I.e., if at the time of the taking of the handful the remainder was intact, it is immaterial if later it was found to have diminished, and it may be eaten; R. Jannai accordingly is in conflict with Ze'iri. Rashi, however, gives another interpretation according to which R. Jannai is in agreement with Ze'iri: the meal-offering was once whole, i.e., at the time of the burning of the handful.');">²⁸</span>
