The Destruction of Sennacherib by Lord Byron

The Assyr/ ian / came down / like the wolf / on the fold,
And his coh/ orts were / gleaming / in pur/ple and gold;
And the sheen /of their spears / was like stars / on the sea,
When the blue / wave rolls / nightly / on deep / Galilee.

Like the leaves / of the for/est when sum/mer is green,
That host / with their ban/ners at sun/set were seen:
Like the leaves /of the for/est when aut/umn hath blown,
That host / on the mor/row lay with/ered and strown.

For the Ang/el of Death / spread his wings / on the blast,
And breathed / in the face / of the foe / as he passed;
And the eyes / of the sleep/ers waxed / deadly / and chill,
And their hearts / but once heaved, / and for ev/er grew still!

And there / lay the steed / with his nost/ril all wide,
But through / it there rolled / not the breath / of his pride;
And the foam / of his gasp/ing lay white / on the turf,
And cold / as the spray / of the rock-/ beating surf.

And there / lay the rid/er distort/ed and pale,
With the dew / on his brow, / and the rust / on his mail:
And the tents / were all sil/ent, the bann/ers alone,
The lan/ces unlift/ed, the trum/pet unblown.

And the wid/ows of Ash/ur are loud / in their wail,
And the id/ols are broke / in the temp/le of Baal;
And the might / of the Gen/tile, unsmote / by the sword,
Hath melt/ed like snow / in the glance / of the Lord!
