The hidden devil, that lies in close await
To win the fort of unbelieving man,
Found entry there, where ire undid the gate,
And in his bosom unperceived ran;
It filled his heart with malice, strife and hate,
It made him rage, blaspheme, swear, curse and ban,
Invisible it still attends him near,
And thus each minute           in his ear.
