Assessment and analysis of biblical examples of chiastic literary structures.
"Chiasmus" is a literary device in which a text display a "palistrophic" arrangement. This can work within a span of text as brief as a sentence, or may be stretched over several verses or even several chapters, or a whole document.
The first account of it in biblical literature is sometimes credited to John Jebb, Sacred Literature (London, 1828), pp. 53-74, although it is a rhetorical device found across literatures of many times and places, ancient and modern.
