Speak of the devil, and he shall appear.
The devil can cite Scripture for his purpose.
The devil has his elect.
The devil is smooth as silk and twice as slippery.
The devil's in the house of the rising sun.
The devil is in the details.
Better to reign in Hell than serve in Heaven.
Fear the devil, but fight him with the cross.
A devil is still a god's creature.
The devil's voice is sweet to hear.
Give the devil his due.
