Which poet is associated with the phrase "Out of a grave I come to tell you this"?

The phrase "Out of a grave I come to tell you this" is associated with the poet Walt Whitman. This line reflects the themes of death, resurrection, and the deep connection between the past and present, which are prevalent in Whitman’s work. His poetry often explores the idea of the self as part of the collective human experience, and this line captures that sense of continuity through time, as if the voice of the poet transcends death to impart important truths to the living.

While other poets like Thomas Gray, Emily Dickinson, and the poet Robinson engage with themes of mortality and nature, Whitman's unique ability to blend the personal with the universal, especially through the lens of death and rebirth, makes this line distinctly his. The resonance of Whitman's voice serves to inspire a deeper contemplation on existence, making the correct association clear.
