The answer is:
In the excerpt from the modernist poem "The Love Song of J. Alfred Prufrock," by T. S. Eliot, the speaker makes a biblical allusion when he mentions a prophet and then Lazarus.
First, he does not want readers to mistake him for a prophet, although he has cried, fastened and prayed. Besides, he suggests he has not been beheaded and had his bald head on a platter, referring to prophet John the Baptist's death.
Finally, he alludes to poor Lazarus, who died and went to heaven. Thus, he compares Dives' request to Abraham to resurrect Lazarus to the speaker's question or matter he is afraid to risk.
