Rashi
When its branches dry out The branches of its roots. Comp. (Ps. 80:12) “It sent forth its branches (קְצִירֶיהָ).” Also (Job 14:9): “And produce branches (קָצִיר).” I.e., when the little merit that Edom has for honoring his father, is depleted, then its branches shall be broken.
Ibn Ezra
קצירה The bough30A. V. The boughs. thereof. Comp. בקצירי In my branch (Job. 29:19).
Rashi
women shall come and ignite it A people weak as women shall ignite them. Jonathan renders in this manner. מְאִירוֹת means ‘ignite.’ Comp. (Mal. 1:10) “And you shall not light (תָּאִירוּ) My altar in vain.” Dunash too interpreted it in this manner, for since the wood will be dry, it will be easy to ignite. Menahem, however, interpreted it to mean ‘gather.’ Comp. (Song 5:1) “I gathered (אָרִיתִי) my myrrh.” Also (Ps. 80:13): “All passersby gathered from it (וְאָרוּהָ).” (Machbereth Menahem p. 32) Dunash replied, “Does it not say, ‘When its branches dry out’? And with dry grapes, no one gathers fruit.” (Teshuvoth Dunash p. 45)] Likewise, our Sages, who prohibited accepting charity from them because of this reason, for they stated in Baba Bathra ch. 1, (10b,) “Does he not believe, ‘When its branches dry out, they shall be broken?’”
