'the might of the Gentile, unsmote by the sword, Hath melted like snow in the glance of the Lord!' Although the Assyrians couldn't be defeated by weaponry, one simple look from God killed them all. This demonstrates the sheer power of God and how he has more 'might' than anyone. It also demosntrates God's ability to take away what people have pride over, in this case, the Assyrians' might.
