C. F. Keil and Franz Delitzsch on Deuteronomy 23:24-25

Deu 23:24-25

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).
