Western Tack For Sale

Sergeant
Doubtful it stood;
As two spent swimmers, that do cling together
And choke their art. The merciless Macdonwald--
Worthy to be a rebel, for to that
The multiplying villanies of nature
Do swarm upon him--from the western isles
Of kerns and gallowglasses is supplied;
And fortune, on his damned quarrel smiling,
Show'd like a rebel's whore: but all's too weak:
For brave Macbeth--well he deserves that name--
Disdaining fortune, with his brandish'd steel,
Which smoked with bloody execution,
Like valour's minion carved out his passage
Till he faced the slave;
Which ne'er shook hands, nor bade farewell to him,
Till he unseam'd him from the nave to the chaps,
And fix'd his head upon our battlements.

And I can't help her, can you help me to explain it to her, she's really getting on nerves!

Thanks
