Verse 5
The stout-hearted are spoiled - The boasting blasphemers, such as Rab-shakeh, and his master Sennacherib, the king of Assyria.
They have slept their sleep - They were asleep in their tent when the destroying angel, the suffocating wind, destroyed the whole; they over whom it passed never more awoke.
None of the men of might - Is not this a strong irony? Where are your mighty men? their boasted armor, etc.?
