Scholars have recognized "Walden"’s use of Biblical allusions. Such allusions are useful tools to convince readers because the Bible is seen as a principal book of truth. According to scholar Judith Saunders, the signature Biblical allusion identified in the book is, “Walden was dead and is alive again.” This is almost verbatim from Luke 15.11-32. Thoreau is personifying Walden Pond to further the story relevant to the Bible. He compares the process of death and rebirth of the pond to self-transformation in humans.
