The Wild Knight and Other Poems/Thou Shalt Not Kill a Certain Evening

by Gilbert Keith Chesterton

I had grown weary of him; of his breath
And hands and features I was sick to death.
Each day I heard the same dull voice and tread;
I did not hate him: but I wished him dead.
And he must with his blank face fill my life -
Then my brain blackened; and I snatched a knife.

But ere I struck, my soul's grey deserts through
A voice cried, 'Know at least what thing you do.'
'This is a common man: knowest thou, O soul,
What this thing is? somewhere where seasons roll
There is some living thing for whom this man
Is as seven heavens girt into a span,
For some one soul you take the world away -
Now know you well your deed and purpose. Slay!'

Then I cast down the knife upon the ground
And saw that mean man for one moment crowned.
I turned and laughed: for there was no one by -
The man that I had sought to slay was I.
