עַתָּה֙ הֲמִבַּלְעֲדֵ֣י יְהוָ֔ה עָלִ֛יתִי עַל־הַמָּק֥וֹם הַזֶּ֖ה לְהַשְׁחִת֑וֹ יְהוָה֙ אָמַ֣ר אֵלַ֔י עֲלֵ֛ה עַל־הָאָ֥רֶץ הַזֹּ֖את וְהַשְׁחִיתָֽהּ׃
Am I now come up without the LORD against this place to destroy it? The LORD said unto me: Go up against this land, destroy it.’
Rashi on II Kings
Is it with other than Adonoy. Did I come without permission? Yeshayohu already prophesied in the days of Achaz your father, ”Adonoy shall bring upon you and upon your people, etc., the king of Ashur.”17Yeshayohu 7:17. Radak cites another verse from Yeshayohu's prophecy, “and therefore the LRD is bringing upon them the mighty and abundant waters of the river, the king of Ashur, etc.,” in Yeshayohu 8:7. Sancheiriv therefore believed that he was acting with Divine approval.
