As

“Listen: this story's one you ought to know,
You'll reap the consequence of what you sow.
This fleeting world is not the world where we
Are destined to abide eternally:
And for the sake of an unworthy throne
You let the devil claim you for his own.
I've few days left here, I've no heart for war,
I cannot strive and struggle any more,
But hear an old man's words: the heart that's freed
From gnawing passion and ambitious greed
Looks on kings' treasures and the dust as one;
The man who sells his brother, as you've done,
For this same worthless dust, will never be
Regarded as a child of purity.
The world has seen so many men like you,
And laid them low: there's nothing you can do
But turn to God; take thought then for the way
You travel, since it leads to Judgment Day”
