Reference for Menachot 216:21

אמר שמואל חוששין אף לבינוני דלגבי קטן עין יפה הוא

[THAT HE HAD SPECIFIED ONE] BUT I DO NOT KNOW WHICH IT IS', THE LARGEST ONE AMONG THEM MUST BE HOLY. <big><b>GEMARA: </b></big>[THE LARGER ONE IS HOLY.] We thus see that he that sanctifies sanctifies in a liberal spirit.
