In biblical studies, inclusio is a literary device based on a concentric principle, also known as bracketing or an envelope structure, which consists of creating a frame by placing similar material at the beginning and end of a section, although whether this material should consist of a word or a phrase, or whether greater amounts of text also qualify, and of what length the frames section should be, are matters of some debate. Inclusio is found in various sources, both antique and new. The purpose of an inclusio may be structural - to alert the reader to a particularly important theme - or it may serve to show how the material within the inclusio relates to the inclusio itself. An important case of this occurs in the Gospel of Mark's treatment of the "Cursing of the Fig Tree" and the "Cleansing of the Temple" (Chapter 11). By giving the first half of the story before the Cleansing of the Temple, and the conclusion after, Mark creates a "frame" that effectively highlights that he wants the Cleansing of the Temple to be seen in light of the Cursing of the Fig Tree - i.e. Jesus' actions in the Temple are not just a reform measure, but a judgment against it. In the Hebrew Bible (the Old Testament) While this may not be evident to many of the Bible's modern day readers, the Hebrew Bible is full of literary devices, some of which, having fallen out of favor over the years, are lost on most modern readers. Inclusio, of which many instances can be found in the Bible, is one of these, although many instances of its usage are not apparent to those reading translations of the Bible rather than the Hebrew source. Particularly noteworthy are the many instances of inclusio in the Book of Jeremiah. A rather far-flung example of inclusio in the Book of Jeremiah can be found in its first section, chapters 1–24, which are enveloped both by a similar question in the first and last episode (1:11, 24:3), and by similar imagery—that of almond rods and baskets of figs. Inclusio may also be found between chapters 36 and 45, both of which mention Baruch ben Nerya, to whom Jeremiah's prophecies were entrusted. Bracketing can also be seen in The Lord's sayings in 1:10 and 24:6. Indeed, the whole book save for its last (52nd) chapter—which some claim was
