וַיֹּֽאמְר֨וּ זִקְנֵ֣י הָעֵדָ֔ה מַה־נַּעֲשֶׂ֥ה לַנּוֹתָרִ֖ים לְנָשִׁ֑ים כִּֽי־נִשְׁמְדָ֥ה מִבִּנְיָמִ֖ן אִשָּֽׁה׃
회중 장로들이 가로되 베냐민의 여인이 다 멸절되었으니 이제 그 남은 자들에게 어떻게 하여야 아내를 얻게 할꼬
Rabbeinu Bahya
The words להעלות נר, are sort of a headline. The word נר means “lamps” (pl.) just as when Yaakov told Esau that he had acquired שור וחמור (Genesis 32,6) he did not mean that he had acquired only one of each, but that he had made acquisitions of these respective species of domestic animals. We find a similar use of the “singular” אשה, in Judges 21,16, where the words כי נשמדה מבנימין אשה do not mean that “a woman of the tribe of Benjamin had been killed,” but that ”all the women of Benjamin had been destroyed.”
