Heaven has an end in all: yet, you that hear me, This from a dying man receive as certain: Where you are liberal of your loves and counsels Be sure you be not loose; for those you make friends And give your hearts to, when they once perceive The least rub in your fortunes, fall away Like water from ye, never found again But where they mean to sink ye.
Heaven has a purpose in everything: still, you who hear me, Know this for certain from a dying man: Where you are generous with your love and advice, Be sure you aren't careless; for those you make friends And give your hearts to, once they see The slightest misfortune in your life, will turn away Like water flowing from you, never to return Except to drown you.
The Duke of Buckingham · Act 2, Scene 1
Buckingham, proceeding to his execution with dignity, warns the world about the nature of courtly friendship and sudden reversals. The image of friends falling away 'like water' is the play's clearest articulation of how quickly fortune turns and how little power or virtue can protect you. He speaks as a dying man, lending his words prophetic weight.
