ROMEO There is thy gold, worse poison to men's souls, Doing more murders in this loathsome world, Than these poor compounds that thou mayst not sell. I sell thee poison; thou hast sold me none. Farewell: buy food, and get thyself in flesh. Come, cordial and not poison, go with me To Juliet's grave; for there must I use thee.
