신명기 23:25의 주석

כי תבא בכרם רעך WHEN THOU COMEST INTO THE VINEYARD OF THY FELLOW MAN, [THEN THOU MAYEST EAT GRAPES AT THY FILL] — Scripture is speaking of a laborer (who is engaged in gathering in the grapes, but not of one who is doing other work in the vineyard, nor of one who enters the vineyard with no intention to do work; cf. Rashi in the next passage) (Bava Metzia 87b).

ואל כליך לא תתן, "but you may not put any of them into your vessel." The Torah prefaces the word כליך with the conjunctive letter ו to remind us that there was another commandment which immediately preceded this commandment. We refer to the prohibition to overeat from the grapes of the vineyard of your employer. We derive this prohibition from the fact that the Torah wrote שבעך "to your satisfaction," i.e. not more than your fill. After this the Torah added: "neither shall you put any into your vessel."

כי תבא בכרם רעך, “when you enter the vineyard of your fellow,” The Torah speaks of a worker hired to help with the harvesting of the grapes (Baba Metzia 87). Our sages there continue to understand the word כי תבא עליו השמש (24,15) which clearly speaks of a worker, as proof that here too (only) a worker is meant. Otherwise, everyone could help himself to the grapes in any vineyard any time. This is also the way Onkelos translates our verse, i.e. ארי תתגר, “when a trader,” i.e. someone who has legitimate business in that vineyard.
