2. Repetition: The speaker repeats the phrase "Death, be not proud" throughout the sonnet. This repetition emphasizes the speaker's defiance of death and his determination to overcome it.
3. Paradox: The speaker argues that death is not powerful or proud, but rather weak and powerless. This is a paradox, because death is usually seen as a powerful force that cannot be overcome. By arguing that death is weak, the speaker is able to undermine its power and make it seem less threatening.
