Reference for Menachot 12:2

אי הכי התם נמי ליתני אחד חטאת חלב ואחד כל הזבחים שקבלו דמן זר ואונן ולימא לר"ש אצטריך

Now I might have thought that, since R'Simeon laid down the principle 'So that his offering be not sumptuous', it should be valid even where an unfit person took out the handful, we are therefore informed [that even according to R'Simeon it is invalid]. If so, there<span class="x" onmousemove="('comment',' In Zeb., at the opening of Chap. II, 15b, the Mishnah states: 'All offerings are invalid if a non-priest . . received the blood'. That Mishnah, following the example of our Mishnah, should surely have specified the case of the sin-offering, thereby indicating that it was also in accordance with R. Simeon's view.');">¹</span>
