申命記 24:20 註釋：Rashi, Ibn Ezra, Rabbeinu Bahya & Chizkuni

לא תפאר — This means: thou shalt not entirely remove its (the olive tree’s) glory (תפארת) from it, i.e., its fruit (Chullin 131b). Hence they (the Rabbis) derived the law that one must leave פאה (some quantity of fruit) also on fruit-trees for the poor (cf. Mishnah Peah 4:1).

When you shake Compare “threshing wheat” [Judges 6: 11], where the verb appears in the qal form. In “beaten out with a staff” [Isaiah 28: 27] the same verb appears in the nif‘al form.

לא תפאר אחריך, “do not go over them again;” according to the plain meaning of the text the meaning is: “do not search the branches.” The word occurs in this context in Ezekiel 17,6: “it produced branches.”

אחריך BEHIND THEE — This implies שכחה (forgotten fruit; that if he forgets to remove some fruit from the orchard, he must leave it for the poor).
