Chiastic Structure

Definition

A chiasm is an ancient literary device in which a sequence of ideas is presented and then reversed, with a center point that often functions as the conceptual climax. The pattern typically takes the form ABCBA or ABCDCBA, mirroring around a central element. Hebrew narrative, poetry, and prophecy use chiasms extensively. Once you see them, the structure of biblical books and passages opens up in ways linear Western reading misses.

Key proponents

Modern

Marty Solomon; chiasm is a constant feature of his teaching.
Tim Mackie & Jon Collins (BibleProject); their literary-design videos surface chiasms throughout scripture.
Robert Alter, The Art of Biblical Narrative; classical literary treatment.
David A. Dorsey, The Literary Structure of the Old Testament; comprehensive structural analysis.
Mary Douglas, Leviticus as Literature; chiasm in legal and priestly texts.
Yehuda Radday, pioneering Hebrew literary studies.

Premodern witnesses

The rabbinic tradition has long read Hebrew narrative attentive to symmetric structure. Bereshit Rabbah and the broader midrashic literature pick up on patterning in Genesis without using the modern term.
Augustine noted literary structures in Scripture in his De Doctrina Christiana, though without naming chiasm specifically.
Origen (c. 185 to 253) and the medieval mystical readers (especially the Victorine school) attended to the layered literary structure of biblical text in ways that anticipate later structural-literary methods.
The modern recovery of chiasm as a central feature of Hebrew literature (Lowth in the 18th century, Lund in the 20th, Alter and others more recently) is recovering attentiveness that the ancient writers and readers took for granted.

Core insights

Center as climax. In a chiastic structure, the center is typically the most important element, not the end. This is the opposite of how Western argumentative writing works (where the conclusion is the climax). For Hebrew authors, the structure points inward. To find the “punch” of a passage, look at the middle.

Mirror as meaning. The mirroring isn’t decoration. The matching elements (A and A’, B and B’) often comment on each other, modify each other, or expose contrasts. Reading chiastically means reading both halves in conversation rather than purely sequentially.

Pervasive in the Pentateuch. Genesis is full of chiasms. The flood narrative (Genesis 6-9) is one extended chiasm centering on God remembering Noah (8:1). The toledot structure of Genesis itself is debated chiastically. Leviticus is one massive chiasm centered on the Day of Atonement (Leviticus 16). The Pentateuch as a whole has been read as chiastic, with Leviticus at its center.

Genesis 1’s two triads. The seven-day structure is partly chiastic in its days-1-3 / days-4-6 mirroring (form, then fill), with day 7 as the resolving culmination outside the parallel pattern. Form (light, sea-and-sky, land) is matched by fill (lights, fish-and-birds, animals-and-humans). Day 7 stands alone, the deity entering the temple.

Genesis 2-3 is a tightly chiastic narrative. The arc moves from Adam alone, to Adam and Eve in unity, to Eve tempted, to both eating, to both judged, to both clothed, to both exiled. The center is the act of eating. Chiastic readings of Genesis 3 highlight the inversion: command is reversed at the center, and consequences ripple outward in mirror.

Mark’s Gospel is chiastic. Many scholars have argued for an extensive chiasm in Mark, with the transfiguration or the messianic confession at the center. Other Gospels and epistles show similar patterns at sub-passage levels.

Hebrew poetry uses the device intensely. Psalms in particular often display chiastic patterns. Psalm 23 has a chiastic structure centering on the valley. Psalm 67 is a clean chiasm. The Hebrew poetic line itself (parallelism) is a micro-chiasm: A and A’ on the same idea, mirrored.

Implications. Recognizing chiastic structure changes interpretation. It identifies what the author thought was central. It reveals connections between elements that linear reading misses. It honors the literary skill of the biblical authors. And it pushes against a flat, point-by-point reading toward a more dynamic, structural one.

Cautions. Not every passage is chiastic. The technique can be over-applied, with interpreters straining to find chiasms where none exist. A chiasm should be detectable from clear textual cues (verbal parallels, structural markers), not invented to fit a pet reading. Where the chiastic structure is genuine, it’s usually obvious in the original Hebrew or Greek.

Where it shows up in Scripture

Genesis 2-3, garden narrative.
Genesis 6-9, flood narrative (centered on Genesis 8:1, “God remembered Noah”).
Genesis 11:1-9, tower of Babel.
Leviticus (whole book, centered on chapter 16, Day of Atonement).
Numbers (multiple chiasms across the wilderness narratives).
Deuteronomy (the law sections).
Ruth (whole book, centered on Boaz and Ruth’s encounter).
Esther (whole book, centered on the king’s sleepless night).
Many psalms, including Psalm 23 and Psalm 67.
Mark’s Gospel, arguably whole-book.
John 6, the bread-of-life discourse.
Revelation, multiple nested chiasms.

Common misreadings to avoid

Don’t force chiasms where they don’t exist. The technique is a tool, not a key to every passage.
Don’t make the center exhaust the passage. Even when there’s a chiastic center, the surrounding material carries meaning too.
Don’t expect symmetry to be perfect. Hebrew chiasms often have asymmetries, intentional breaks, or extra elements. The pattern is a guide, not a law.
Don’t substitute structure for content. Identifying a chiasm tells you what the author emphasized; it doesn’t tell you what the emphasis means.
