וַֽיַּחֲזִ֜קוּ אִ֣ישׁ ׀ בְּרֹ֣אשׁ רֵעֵ֗הוּ וְחַרְבּוֹ֙ בְּצַ֣ד רֵעֵ֔הוּ וַֽיִּפְּל֖וּ יַחְדָּ֑ו וַיִּקְרָא֙ לַמָּק֣וֹם הַה֔וּא חֶלְקַ֥ת הַצֻּרִ֖ים אֲשֶׁ֥ר בְּגִבְעֽוֹן׃
각기 적수의 머리를 잡고 칼로 적수의 옆구리를 찌르매 일제히 쓰러진지라 그러므로 그곳을 헬갓 핫수림이라 일컬었으며 기브온에 있더라
Rashi
The Plain of Swords. Yonasan translates the plain of Killing on account of the swords just like you say [in Scriptures] (Tehilim 89, 44)2Rashi is showing how the word צוּר, sharpness, is used in reference to a sword. "You also turned back the sharpness of his sword."
