Revoke thy gift,
Or whilst I can vent clamor from my throat,
I’ll tell thee thou dost evil.

– William Shakespeare

King Lear, Act 1, Scene 1. In his bid to get King Lear to do the right thing, Kent bluntly demands that he revoke his gifting the kingdom to his two elder daughters and disowning Cordelia. Otherwise for as long as he is able to speak he will keep telling that Lear has done an evil thing.
