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

what does the bible say?

Synonymous parallelism, a key feature of Hebrew poetry, pairs two lines so that the second line repeats or emphasizes the first with slightly different words or imagery. The purpose is to convey a single idea in two distinct ways. This device appears throughout the Psalms. An example is, “The heavens declare the glory of God, and the sky above proclaims his handiwork” (Psalm 19:1). Both lines express the same truth—that creation displays God’s majesty—but with two complementary images. Another example is found in Psalm 24:1, which reads, “The earth is the LORD’s and the fullness thereof, the world and those who dwell therein.” The second line expands on the first, clarifying that everything in creation, including its inhabitants, belongs to God. For more examples, see Psalm 93:3–4, 103:10, and 118:8–9. Proverbs also contain many examples, such as Proverbs 3:11 and 11:25. The prophets used this style as well, with instances in Isaiah 55:6 and Micah 4:3. Note that these paired lines are not unnecessary repetition, but a way to encourage deeper reflection on a truth by viewing it from multiple perspectives.

from the old testament

• Synonymous parallelism involves placing two lines side by side so that the second repeats or emphasizes the meaning of the first using different words or images. This forms a couplet that highlights a single idea through repetition with variation. This method is part of the larger family of poetic parallels described by Robert Lowth, who also identified antithetical, emblematic, and synthetic patterns. In the synonymous type, both lines convey the same core idea, allowing the reader to encounter the thought twice and underst and it more clearly.
• The Psalms provide clear examples. Psalm 19:1 states, “The heavens declare the glory of God, and the sky above proclaims his handiwork.” Both lines express the same truth—that the created world reveals God’s greatness—but they use different words to enhance the mental imagery. Psalm 24:1 does something similar: “The earth is the LORD’s and the fullness thereof, the world and those who dwell therein.” The second line adds clarity, showing that not only the land, but also its inhabitants, belong to God. These paired lines don’t introduce new ideas but reinforce the main point by restating it with slight differences.
• Wisdom sayings also use synonymous parallelism. Proverbs 3:11 states, “My son, do not despise the LORD’s discipline or be weary of his reproof.” The two lines mirror each other, using paired words—“despise” and “be weary,” “discipline” and “reproof”—to deliver a single message about accepting God’s correction. Proverbs 11:25 also employs two similar lines to emphasize the blessing of generosity: the one who refreshes others will himself be refreshed. In both cases, the repetition helps make the lesson easier to remember.
• Isaiah also employs this device in his preaching. Isaiah 55:6 urges, “Seek the LORD while he may be found; call upon him while he is near.” Both imperatives convey one command: to turn to the LORD without delay. The repetition emphasizes the urgency by presenting the call in two forms. In this way, Isaiah uses parallel lines to reinforce a single truth so that the listener cannot miss its significance.
• These examples are just a small sample. Synonymous parallelism is woven throughout Israel’s poetry, wisdom, and prophetic writings, appearing in prayers, songs, and laments across the Scriptures. Additional examples include Job 3:11–12, Lamentations 3:59–60, Hosea 6:3, and Nahum 1:5. It appears often because it was a common form embedded in Hebraic thought and was therefore useful for helping the Israelites underst and biblical teachings.

from the new testament

• Synonymous parallelism is primarily found in the Old Testament since it is a feature of Hebrew, 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. For example, one common technique is synonymous parallelism, where a thought is repeated in different words to emphasize its importance. 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.
