Analysing "So, we'll go no more a-roving" by Lord Byron

I've seriously struggled to find useful notes on this poem - I don't need anything on the meaning, just the language-type analysis that I would put in an essay. For example the frequent use of enjambment.
Here's the poem:
SO, we'll go no more a-roving
So late into the night,
Though the heart be still as loving,
And the moon be still as bright.

For the sword outwears its sheath,
And the soul wears out the breast,
And the heart must pause to breathe,
And love itself have rest.

Though the night was made for loving,
And the day returns too soon,
Yet we'll go no more a-roving
By the light of the moon.

It would be so helpful if anyone could analyse some of this?
