If the fig harvest was finished and he watches his field because of grapes, grape harvest and he watches his field because of vegetables, if a worker enters there and the owner is offended, they are forbidden because of robbery³⁸(There is a similar text in Tosephta Ma’serot 3:12 and Babli Pesaḥim 6b, but it deals with the obligation to give tithes.) By Biblical ordinance (Deut. 23:25), a worker is entitled to eat from the produce he is harvesting. This implies that without the owner’s consent he cannot eat from produce he is not harvesting. Hence, if the owner objects to his workers going through those parts of his property that are already harvested, the owner retains all property rights to the unripe produce still standing on the field and, a fortiori, the unripe produce is not abandoned, may not be taken by other people, and is not freed from the obligations of heave and tithes..

MISHNAH: The following eat by Torah law¹⁵The agricultural worker empowered by Deut. 23:25–26 to eat from grain and grapes.: He who works on produce connected to the ground at the completion of work¹⁶The only time he may eat from standing produce is at harvest time if he is occupied in harvesting., or separated from the ground before the completion of work¹⁷As long as the produce is not subject to the laws of tithing, i. e., ready to be stored., only things grown from the earth¹⁸The worker at a hydroponic farm has no right to eat from the produce, nor may the worker in a dairy drink from the milk..
But the following may not eat: He who works on produce connected to the ground before the completion of work¹⁹The agricultural worker during the growing season., or separated from the ground after the completion of work²⁰The worker on food after it became subject to the laws of tithing., or things not grown from the earth¹⁸The worker at a hydroponic farm has no right to eat from the produce, nor may the worker in a dairy drink from the milk..
If he was working with his hand but not with his feet, with his feet but not with his hands, even with his shoulder, he may eat. Rebbi Yose ben Rebbi Jehudah says, only if he works with hands and feet²¹Like the harvester of grain or grapes mentioned in the verse..

HALAKHAH: “The following eat by Torah law,” etc. Rebbi La said, “if you come into your neighbor’s vineyard.²²Deut. 23:25: “If you come into your neighbor’s vineyard, you may eat grapes to satisfy yourself.” What else is there to eat in a vineyard?” Could anybody think that he would eat wood or stones? Why does the verse say “grapes”? That he may not skin figs or suck grapes²³Different, tannaïtic, arguments are in the Babli 87b; Ma‘śerot 2:7 (Notes 142–149); Sifry Deut. 266..
