Take full effect—the devil never dreams:
Watchful and changeful through the world he goes,
And few can trace this deadliest of their foes;
But I detect, and at his work surprise,
The subtle serpent under all disguise.

—'A saint elect, you can have nought to seek;

Why all this labour in so plain a case—
Such care to run, when certain of the race?'
