What is the gist of Hashem's words?
Radak: Ashur and Egypt will be wiped out, for they did not know Me. You will know that Hashem does evil to whom He wants, and benefits who He wants, i.e. the residents of Yerushalayim. Melech Ashur, who destroyed Yisrael (the 10 tribes), [the rest of] Yehudah and Egypt, will come to destroy Yerushalayim. He will not be able to, for Hashem will not want.
