I need one line for this poem.. Just one line, not two. I'm leaning towards the word 'SPAN' but don't know a good way to use it. Can you please help me out?

This Lost Lamb
Written by Adam M. Snow

Oh by the morning struck of day
and by the calm obscured of night
my heart is Yours O' God I pray
grant this lost lamb Your holy sight

Give this lost lamb the sight to see
the truth that lies the love of Thee
let me see the world through Your eyes
and make O' God, this dumb man wise

Grant this lost lamb the words to speak
the Word O' God of Yours to man
the Word of truth for which they seek

You can do it on how it's structured, ie., poetic devices etc., (figurative language), which includes the theme and what a poem means. To get the theme and meaning, find any metaphors and what they mean which usually opens a poem up.

When you left
And when you were still here
I already knew;
Adieu!
You won't touch me again
Or send me any messages
Or call.
It is clear to me,
That things are no longer the same
And that there isn't anything.

It was nice and sweet
You touched me with warm hands
In precise locations
But your bastard's smile isn't leaving anything hidden.
You leave me with nothing.

We played and that enough,
One should know when to fold back as well.
You won, my dear
You won.

And I don't care.
