וַיֹּֽאמְרוּ֙ דָּ֣ם זֶ֔ה הָחֳרֵ֤ב נֶֽחֶרְבוּ֙ הַמְּלָכִ֔ים וַיַּכּ֖וּ אִ֣ישׁ אֶת־רֵעֵ֑הוּ וְעַתָּ֥ה לַשָּׁלָ֖ל מוֹאָֽב׃
가로되 이는 피라 필연 저 왕들이 싸워 서로 죽인 것이로다 모압 사람들아 이제 노략하러 가자 하고
Ibn Ezra
חרב יחרבו They will be slain. This verb is derived from חרב sword; comp. החרב נחרבו they are surely slain. (2 Kgs. 3:23). Some explain it they shall be utterly wasted, and compare it with חרבן destruction. I prefer the first explanation.
