The title comes from the Bible, the Book of Numbers 22:23, where Balaam does not see the angel of the Lord but his donkey does. The Bible is heavily referenced throughout the novel. In an interview with BOMB magazine, Cave noted, “There are a number of voices in the book: first person narrative by Euchrid, third person authorial voice, quotations usually from the Bible, either real or ersatz, constant changes in tone or approach to language, depending on who is talking. When I first started the book there were certain elements I wasn’t interested in reading about. When you read a novel, you have to wade through the setting up of the scene before the story starts. So I wrote a long prologue. It has no action. It includes documentary, poetry, maps and charts, in very short chapters. Once this is done, the actual story begins. The voice then changes between the narrator’s truth and Euchrid’s delusionary truth. The final book is Euchrid’s monologue which runs to the climax” The book is narrated in the protagonist's silent Southern drawl, which Cave writes in eye dialect.
