當它的枝條枯乾時，就必被折斷；婦女們前來，將它點火焚燒。因為這是一個沒有悟性的民族，所以造他的那位必不憐憫他，塑造他的那位必不施恩給他。
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

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?’”
