Deuteronomy 23:24

“When thou comest into thy neighbour's vineyard, then thou mayest eat grapes thy fill at thine own pleasure--Vineyards, like cornfields mentioned in the next verse [Deu 23:25], were often unenclosed. In vine-growing countries grapes are amazingly cheap; and we need not wonder, therefore, that all within reach of a person's arm, was free; the quantity plucked was a loss never felt by the proprietor, and it was a kindly privilege afforded to the poor and wayfaring man. Next: Deuteronomy Chapter 24”

“At thy pleasure - Which was allowed in those parts, because of the great plenty and fruitfulness of vines there. Next: Deuteronomy Chapter 24”

“23:24 your neighbor’s vineyard: In a certain sense, God owned all the land and provided it to its human occupants. Therefore, no one had the right to make an exclusive claim to it. On the other hand, renters had rights to privacy and to a measure of control over what had been allotted to them. Trespassing was permitted within this context but not with the intention of theft. One could, however, pluck a few grapes or kernels of grain to eat along the way (see Matt 12:1-8; Mark 2:23-28; Luke 6:1-5).”

“thou mayest: Rom 12:13; Co1 10:26; Heb 13:5 Deuteronomy 23:25”

“In the vineyard and cornfield of a neighbour they might eat at pleasure to still their hunger, but they were not to put anything into a vessel, or swing a sickle upon another's corn, that is to say, carry away any store of grapes or ears of corn. כּנפשׁך, according to thy desire, or appetite (cf. Deu 14:26). "Pluck the ears:" cf. Mat 12:1; Luk 6:1. \- The right of hungry persons, when passing through a field, to pluck ears of corn, and rub out the grains and eat, is still recognised among the Arabs (vid., Rob. Pal. ii. 192).
