What's a Chiasm?

A chiasm (or chiasmus if you rather) is a writing style that uses a unique repetition pattern for clarification and/or emphasis. Chiasm is pronounced ky′-az-um. Often called the chiastic (ky′-az-tic) approach or the chiastic structure, this repetition form appears throughout the Bible yet it is not well known. The way you approach the Scriptures should be dramatically enhanced as you learn what a chiasm is, how to recognize chiasms, and how to glean a fresh application from these New or Old Testament passages.

Chiasms are structured in a repeating A-B-C ... C′-B′-A′ pattern:

A    As I was with Moses, so I will be with you. I will never leave you nor forsake you  (5b)
B    Be strong and courageous … be strong and very courageous  (6,7a)
C    Be careful to obey all the law … that you may be successful  (7b)
D    Do not let this Book of the Law depart from your mouth  (8a)
D′ Mediate on it day and night  (8b)
C′ Be careful to do everything written in it … you may be prosperous and successful  (8c)
B′ Be strong and courageous. Do not be terrified; do not be discouraged  (9a)
A′ for the Lord your God will be with you wherever you go.  (9b)
(Joshua 1:5b-9)

Simply put, a chiasm is a repetition of similar ideas in the reverse sequence. The importance of the chiastic structure is found in its hidden emphasis. (See Being an Overcomer for an interpretation of the above chiasm, adapted from my book). And it is not insignificant – I suspect there are more than two thousand examples in the Bible!

Quick Definition of Chiasms

My time in God's Word has become truly exciting as I have learned to uncover the chiastic structure. Over the years, I have studied the Scriptures from many different angles – for me, seeing God's Word from the chiastic perspective has added a great deal of meaning. Yet today, many who have read the Bible are just beginning to discover this even though it was identified over two hundred years ago (see Background of Chiasms).

A chiasm organizes themes much like a sandwich: A) a piece of bread on top, B) mustard, C) a delightful piece of meat, C′) another savory piece of meat, B′) more mustard, and finally A′) another piece of bread on the bottom. Chiasms generally focus on the flavorful meat, but the bread and mustard are necessary for a complete sandwich. Some chiasms do not have a mustard layer, other chiasms have lettuce on both sides of the meat, and some have just one piece of delicious meat.

When God inspired the Hebrew and Greek writers to inscribe their portions of the Scriptures, the chiastic structure was often used to add emphasis. He could not use techniques such as bold, italics, underline, indentation, bullets, or font size to help the reader understand what is important because these were not part of the ancient languages at the time. Instead He often used the structural arrangement of repeated thoughts or phrases to accomplish this emphasis.
