Answer:
Though I have seen my head (grown slightly bald) brought in upon a platter,
To say: "I am Lazarus, come from the dead, Come back to tell you all, I shall tell you all"—
Step-by-step explanation:
The two sections of this excerpt from T.S Eliot's "The Love Song of J. Alfred Prufrock" that contain a biblical allusion are Though I have seen my head (grown slightly bald) brought in upon a platter, and
To say: "I am Lazarus, come from the dead, Come back to tell you all, I shall tell you all"—
From the two sections, allusions are made first of all to John the Baptist whose head was brought on a platter for King Herod and Lazarus who was raised from the dead by Jesus. These are two valid events that happened and are recorded in the Bible.
