Origin: Spoken by Antonio in "The Merchant of Venice", written by William Shakespeare (1564-1616):
Mark you this, Bassanio,
The devil can cite Scripture for his purpose.
An evil soul producing holy witness
Is like a villain with a smiling cheek,
A goodly apple rotten at the heart:
O, what a goodly outside falsehood hath!
If "The devil can cite Scripture for his purpose", why would he do that?
