כִּי־אֵשׁ֙ יָֽצְאָ֣ה מֵֽחֶשְׁבּ֔וֹן לֶהָבָ֖ה מִקִּרְיַ֣ת סִיחֹ֑ן אָֽכְלָה֙ עָ֣ר מוֹאָ֔ב בַּעֲלֵ֖י בָּמ֥וֹת אַרְנֹֽן׃
헤스본의 불이 나오며 시혼의 성에서 화염이 나와서 모압의 아르를 삼키며 아르논 높은 곳의 주인을 멸하였도다
Rashi on Numbers
כי אש יצאה מחשבון FOR A FIRE WILL GO FORTH FROM HESHBON after Sihon captures it,
Rabbeinu Bahya
כי אש יצאה מחשבון, ”for a fire has come forth from Cheshbon.” This is an allusion to Moabites who had dwelled in Chesbon and commenced a revolution against the local king.
