ANTONIO: 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!

Shakespeare
William Shakespeare (1564-1616) English dramatist and poet
Merchant of Venice, Act 1, sc. 3, l. 106ff (1.3.106-111) (1597)
