כִּֽי־לִפְנֵ֤י קָצִיר֙ כְּתָם־פֶּ֔רַח וּבֹ֥סֶר גֹּמֵ֖ל יִֽהְיֶ֣ה נִצָּ֑ה וְכָרַ֤ת הַזַּלְזַלִּים֙ בַּמַּזְמֵר֔וֹת וְאֶת־הַנְּטִישׁ֖וֹת הֵסִ֥יר הֵתַֽז׃
Porque antes de la siega, cuando el fruto fuere perfecto, y pasada la flor fueren madurando los frutos, entonces podará con podaderas los ramitos, y cortará y quitará las ramas.
Rashi on Isaiah
For before the ripening of the harvest of Amalek and of Gog, when he has not yet filled his desire and his hope, that he plans to destroy his brothers.
Rashi on Isaiah
when the blossom is past i.e., when its blossom is past and the grain is close to becoming ripe in its ears and before the buds of his vine become ripening grapes, ripened to the extent of being בֹּסֶר, i.e., when the grapes become as big as a white bean. This is called בֹּסֶר and also גֵּרוּעַ.
Ibn Ezra on Isaiah
גומל Ripening, Comp. ויגמל And it ripened (Num. 17:23). יהיה נצה Will still be in the flower.
