What is the literary device of synthetic parallelism used in Hebrew poetry?

what does the bible say?

Synthetic parallelism is a feature of Hebrew poetry where the second line further develops the idea from the first. It might give a conclusion, add emphasis, or exp and the lesson, so the point lands with greater force. Unlike synonymous parallelism, which repeats the same idea in different words, synthetic parallelism builds on the first line to deepen the meaning. Wisdom books provide many examples. Sometimes, the second line delivers the moral judgment of the first, like when Proverbs 21:4 lists traits of the arrogant and then labels them as sin. Other times, they amplify the point with a “how much more” structure, such as in Proverbs 21:27, where a corrupt motive makes sacrifice even more offensive. Another pattern is a “better…than…” comparison, like Ecclesiastes 7:5, which ranks one option above another. Other examples appear throughout the Old Testament, such as Job 5:17, Psalm 19:7, Isaiah 1:16–17, and Micah 6:8. In each case, the second line develops or reinforces the first, so the idea gains greater weight and clarity. Recognizing this device helps readers see how Hebrew poetry moves an idea forward, emphasizing God’s truth in a memorable way.

from the old testament

• Synthetic parallelism involves pairing lines where the second line expands on the idea of the first. Its progression of ideas makes it especially useful for teaching, as it clarifies the significance or consequences of the first line. For example, Solomon wrote, “Haughty eyes and a proud heart, the lamp of the wicked, are sin” (Proverbs 21:4). The opening line (“Haughty eyes and a proud heart”) describes arrogant postures. The second line (“the lamp of the wicked, are sin”) explains arrogance as sin. It does this by portraying the inner attitude (“lamp”) as guiding a person’s steps. In this example, then, the couplet shifts from describing a person to the implied moral lesson.
• As another example, Solomon also wrote, “The sacrifice of the wicked is an abomination; how much more when he brings it with evil intent” (Proverbs 21:27). The first part (“The sacrifice of the wicked is an abomination”) describes a wrong action, while the second part (“how much more when he brings it with evil intent”) raises the issue by adding a corrupt motive. It uses a classic “how much more” pattern that intensifies the statement. This kind of synthetic parallelism is common in wisdom sayings that compare a basic case, which can be good, bad, or even neutral, to a worse case, aiming to help the reader grow in wisdom (i.e., Proverbs 11:31).
• Ecclesiastes demonstrates another common pattern of synthetic parallelism: the evaluative “better…than…” judgment. For example, Ecclesiastes 7:5 states, “It is better for a man to hear the rebuke of the wise than to hear the song of fools.” The first part (“It is better for a man to hear the rebuke of the wise”) praises difficult yet good advice over the second, shallow option (“than to hear the song of fools”). These comparisons guide the reader toward choosing the wiser course. See, for another example, Proverbs 16:16.
• These examples are just a small sample. Synthetic parallelism appears throughout Israel’s wisdom, songs, and prophetic writings, shaping instruction and exhortation across the Scriptures. Additional examples can be found in Job 5:17, Psalm 19:7, Isaiah 1:16–17, and Micah 6:8.

from the new testament

• Synthetic parallelism is a feature of Hebrew poetry, and the New Testament was written in Greek.

implications for today

The Bible is full of clever ways that help us underst and God’s message. Synthetic parallelism is one of these tools, where the second line carries the thought of the first further. The Scriptures also use contrast, vivid images, acrostics, and repetition—not just to make reading interesting, but to help us remember and grasp what God is saying. These aren’t just stylistic choices; they’re thoughtful tools designed to help us connect with His truth. When you read the Bible, pay attention to how it’s put together. Notice when a writer repeats a phrase or uses a comparison or a striking image. For instance, when a Psalm contrasts the wicked and the righteous, it’s highlighting the differences to guide our understanding of what it means to live rightly. Vivid images in prophecy grab our imaginations and help us feel the message deep in our hearts. Every word and phrase in Scripture has a purpose. So, as you read, ask yourself: Why did the author choose this particular wording? Why is this comparison here? These patterns are God’s way of speaking in a language that we can easily remember and live by. They can help us see the Bible’s message more clearly and grow in our faith.

Recap

understand

• In synthetic parallelism, the second line expands, completes, or intensifies the thought of the first line, rather than merely repeating it.
• Patterns include moral judgments, “how much more” escalation, and “better…than…” comparisons.
• Synthetic parallelism is used widely in wisdom literature, Psalms, and prophecy to teach, guide, and emphasize God’s truth.
