Craig R. Koester points to one literary device at Heb. 9:5. Remarking upon the Greek construction, PERI hWN OUK ESTIN NUN LEGEIN KATA MEROS, he writes:
"The author concludes his description of the furnishings [of the Tabernacle] by commenting that he cannot deal with these things in detail (cf. 11:32). Rhetorically, passing by something without detailed comment was called PARALEIPSIS (Rhet. ad Her. 4.27 Sec. 37' Lausberg, Handbook SS 882-886)." By identifying some aspects of a large topic while refusing to make detailed comment, the speaker alludes to his familiarity with the subject matter, while relativizing its importance. Here, Hebrews makes clear that what is most important is not the sanctuary, but the ministry that takes place within it" (Hebrews: A New Translation with Introduction and Commentary. Anchor Bible Commentary. New York: Doubleday, 2001), p. 404.
George Guthrie likewise supplies these details:
"Most importantly, he [Leon Vaganay] advanced discussion on the structure of Hebrews with his identification of mot-crochets, 'hook words,' in the book. Hook words were a rhetorical device used in the ancient world to tie two sections of material together. A word was positioned at the end of one section and at the beginning of the next to effect a transition between the two" (The Structure of Hebrews, page 12).
One example of a writer employing hook words is Heb. 1:4-5 (which evidently represents the start of a new section), where we find the author using TWN AGGELWN in both verses. TWN AGGELWN thus joins together Heb. 1:1-4 with the following section of Hebrews which begins with Heb 1:5.
According to Richard Lanham, an expert in literary devices, the word "hyperbole" denotes: "Exaggerated or extravagant terms used for emphasis and not intended to be understood literally; self-conscious exaggeration."
Heinrich Lausberg writes: "Hyperbole is an extreme, literally implausible onomastic surpassing of the verbum proprium." Furthermore, "hyperbole is a metaphor with vertical gradations" that stimulates the imagination (Handbook of Literary Rhetoric, section 579).
The September 1, 2002 WT notes that hyperbole is an intentional exaggeration that someone utters for the purpose of emphasis or to make a point. We see vivid examples of hyperbole in the Gospels and Pauline Epistles.
