Isaiah 10:20

In some future day, the remnant (cf. Isaiah 6:13; Isaiah 7:3) who escaped annihilation by the Assyrians would no longer trust in man for deliverance, as Ahaz and Judah did before the Assyrian takeover. They would learn this most important lesson and truly trust in Yahweh, the holy one of Israel. Thus Israel would be the really wise and strong nation, not Assyria (cf. Isaiah 10:13). Israel, as well as Assyria (Isaiah 10:19), would have a remnant left over after the Lord’s destruction of both nations.
