Does anyone know what this Brand New lyric is a reference to?

From the song “Sink” on the new Brand New album “Daisy”

How darkly the dark hand met his end
He was withered and boney, exposed for a phoney
But we heed the last words that he penned
Haste to disgrace the traitor. Do not wait til later
I don’t think that you’ve got to pretend
I see God in birds and Satan in long words
But I know what you need in a friend
So now when I leave you, I hope I won’t see you

I’m trying to figure out this reference, (or if it even is a reference), I’ve seen it online in peoples signatures on message boards etc but can’t find anything else on it. Does anyone know who said it? Or what it’s from?

Thanks!
