 The dwarves taking Bilbo out of his complacent existence has been seen as an eloquent metaphor for the "impoverishment of Western society without Jews".When writing "The Lord of the Rings" Tolkien continued many of the themes he had set up in "The Hobbit".When giving Dwarves their own language (Khuzdul) Tolkien decided to create an analogue of a Semitic language influenced by Hebrew phonology.
