LEAR: Kent, on thy life, no more.
KENT: My life I never held but as a pawn
To wage against thy enemies; nor fear to lose it,
Thy safety being the motive.
LEAR: Out of my sight!

– William Shakespeare

King Lear, Act 1, Scene 1. Kent says that he has never valued his own life except as a pawn (metaphor) Lear could use against his enemies. He pledges that he would protect Lear with his life. But Kent’s protest at Lear’s disowning of Cordelia falls on deaf ears due to Lear’s obstinate pride and failure to see reality. Lear tells the honest and devoted Kent to shut up and get out of his sight. In yet another act of blind folly Lear banishes his most loyal servant and selfless advisor.
