(The Mishnah (daf 48(b)) taught that if an ear of corn of Leket became mixed up with a stack of corn, he should tithe one ear and give it to the poor.) What does he do? He brings two ears and says, "If the better one is Leket, it is Leket and the second ear is Maaser. If the better ear is not Leket, its Maaseros should be on the second one''.

Question: Shouldn't we be concerned that perhaps the second one that was fixed as the Maaseros ear might itself be the Leket?

(R. Yona): (Aside from one ear that he gives to the poor as Leket) he brings a second and third ear and says, "If the first one I gave was the Leket, the second is Maaser; and if the second is the Leket, their Maaseros are in the third ear.
