Reference for Menachot 15:11

ומי א"ר יוחנן הכי והא איתמר הפריש חצי עשרון ודעתו להוסיף רב אמר אינו קדוש ור' יוחנן אמר קדוש ואם איתא לילף מחביתין

But did R'Johanan actually say that?<span class="x" onmousemove="('comment',' That the High Priest's meal-offering is not hallowed if brought half at a time.');">¹⁸</span> Behold it has been stated: If a man set aside [in a vessel of ministry] a half tenth [of flour for his meal-offering]<span class="x" onmousemove="('comment',' The minimum quantity of flour for a meal-offering is one tenth part of an ephah.');">¹⁹</span> intending to add to it [to make up the tenth], Rab says, It is not hallowed; R'Johanan says, It is hallowed.
