Jerome : (Verse 18) And the pride of men shall be humbled, and the lofty heights of men shall be brought low, and the Lord alone shall be exalted in that day, and all idols shall be utterly crushed. Human discourse seems to have reason as long as it is not compared to divine knowledge. But when falsehood approaches truth like straw to fire, it is quickly consumed and perishes, and all the doctrines of falsity, which are now called idols, because they are feigned and fabricated, shall be utterly crushed. — Commentary on Isaiah
