What is considered leket? That which falls at the time of the reaping. [If] he was reaping [and] he reaped a handful [or] plucked a fistful [and] a thorn struck him and [the ear of produce] fell from his hand to the ground, it belongs to the owner.  [From] within the hand and within the sickle, [it belongs] to the poor. [But from] behind the hand and behind the sickle [it belongs] to the owner. [From] the tip of the hand and from the tip of the sickle —- R' Yishmael says: [It belongs] to the poor; [but] R' Akiva says: [It belongs] to the owner.

Ant-holes —- [if] they are within standing grain, they belong to the owner; [if] they are after the reapers, the upper ones belong to the poor and the lower ones belong to the owner.  R' Meir says: It all belongs to the poor, since doubtful leket is considered leket.
