申命記 24:19 註釋：Rashi, Ibn Ezra, Rabbeinu Bahya & Chizkuni

ושכחת עמר [WHEN THOU REAPEST THY HARVEST IN THY FIELD] AND HAST FORGOT A SHEAF … [THOU SHALT NOT RETURN TO TAKE IT] — a sheaf, but not a stack of corn (Sifrei Devarim 283:1). Hence they (the Rabbis) said, “A sheaf that contains two Seahs of grain which one has forgotten in the field, does not come under the term of שכחה (a forgotten sheaf)” (Mishnah Peah 6:6).

in order that He will bless you for you gave of what you only imagine to be yours; but God will give to you of that which is truly His.

לא תשוב לקחתו...למען יברכך ה' אלו-היך, “you must not turn back in order to take it;.....in order that the Lord your G’d will bless you.” G’d assigned a blessing for people who have the right thoughts. Sifri 283 adds that even if the handout, i.e. forgotten sheaf, became the property of the poor without deliberate intent by the farmer who had forgotten it, he will be blessed. How much more will he be blessed when he had arranged for the poor to become the recipient of this sheaf (or coin, etc.)?

בשדה [AND HAST FORGOT …] IN THE FIELD — This apparently redundant word (it has just stated בשדך) is intended to include under this law forgotten “standing corn” (קמה) — that one has forgotten to cut down part of it (Sifrei Devarim 283:2).

לא תשוב לקחתו THOU SHALT NOT GO BACK TO TAKE IT — Hence they (the Rabbis) said: A sheaf that is behind him is considered as שכחה, that which is in front of him is not considered שכחה, for the expression “thou shalt not go back [to take it]” is not applicable to it (Mishnah Peah 6:4; Bava Metzia 11a).
