“ But if he said to him, you may harvest a third for yourself, He is permitted to the gleanings, the forgotten sheaves, and the corner, And forbidden to the tithe of the poor.” Mishnah 6
If he sells his field, the seller is permitted, and the buyer is not. He may not hire a man to work on his portion to have his son collect after him. One who does not allow the poor to glean, or he allows one, and not another, or he helps one, Indeed, he openly steals from the poor, as it is said, “Do not withdraw the eternal boarder.” ”

“ If, during harvesting, a grain’s ear touches the standing crop, If it can be harvested with the standing crop, Indeed, it belongs to the master of the house. And if not, indeed, it belongs to the poor. If a grain’s ear is intermixed in the stack, It must be tithed and one shall be given to the poor. ”

“ If the sheaves are forgotten by workers, And the master of the house did not forget it, Or the master of the house forgot and the workers did not forget it, Or if the poor stood before him, or if the straw was covered, Indeed, this is not forgotten. ”
