Twenty consciences,
That stand ‘twixt me and Milan, candied be they
And melt ere they molest!

– William Shakespeare

The Tempest, Act 2, Scene 1. Antonio is speaking to Sebastian, who asked if he was bothered by his conscience. Antonio replies that if he had twenty consciences they would melt before they would bother him. Antonio is an arch villain and shameless power seeker, who reveals his plan to Sebastian to murder Alonso.
