וְיָדַעְתָּ֣ הַיּ֗וֹם כִּי֩ יְהוָ֨ה אֱלֹהֶ֜יךָ הֽוּא־הָעֹבֵ֤ר לְפָנֶ֙יךָ֙ אֵ֣שׁ אֹֽכְלָ֔ה ה֧וּא יַשְׁמִידֵ֛ם וְה֥וּא יַכְנִיעֵ֖ם לְפָנֶ֑יךָ וְהֽוֹרַשְׁתָּ֤ם וְהַֽאַבַדְתָּם֙ מַהֵ֔ר כַּאֲשֶׁ֛ר דִּבֶּ֥ר יְהוָ֖ה לָֽךְ׃
Sabe, pues, hoy que SEÑOR tu Dios es el que pasa delante de ti, fuego consumidor, que los destruirá y humillará delante de ti: y tú los echarás, y los destruirás luego, como SEÑOR te ha dicho.
Sha'arei Orah
Know that because it consumes every other kind of fire in the world, it is called the Consuming Fire-Aish Ochlah-אש אוכלה. Because of this quality HaShem-יהו״ה, blessed is He, is called a Consuming Fire-Aish Ochlah-אש אוכלה, as stated,157Deuteronomy 4:24; 9:3 “For HaShem-יהו״ה your God is a consuming fire-Aish Ochlah-אש אוכלה; He will destroy them and He will subjugate them.” Because HaShem-יהו״ה, blessed is He, is a consuming fire-Aish Ochlah-אש אוכלה, He therefore can subjugate, humble, and destroy, since with this quality HaShem-יהו״ה, blessed is He, wages war, and it therefore is called terror-Pachad-פחד.
