Eyes, look your last!
Arms, take your last embrace! and, lips, O you
The doors of breath, seal with a righteous kiss
A dateless bargain to engrossing death!

– William Shakespeare

Romeo and Juliet, Act 5, Scene 3. Romeo bids a final farewell to life, as he lies down beside Juliet to embrace her for the last time and kiss her. In a metaphor Romeo’s lips are described as the "doors of breath" which will seal an endless bargain with death, since he is about to end his life and be with her forever in death.
