Topical Lexicon
Location in Scripture

Luke 3:35 records the name Ῥαγαύ (Ragau, Reu) once in the New Testament, embedding him in the genealogy of Jesus Christ.

Historical Background

Reu lived in the generations immediately following the dispersal from Babel (Genesis 11:18-21). The narrative places his life in Mesopotamia, where families were spreading across the earth and the early city-states of Sumer were taking shape. His lifespan of 239 years (per the Masoretic text; 207 in the Samaritan Pentateuch) situates him among the long-lived post-Flood patriarchs whose years diminished steadily toward the lifespan familiar in later biblical history.

Genealogical Role

Reu is the sixth descendant from Shem after the Flood: Shem → Arphaxad → Shelah → Eber → Peleg → Reu → Serug → Nahor → Terah → Abram. In Luke’s record, this chain is preserved flawlessly: “the son of Serug, the son of Reu, the son of Peleg, the son of Eber, the son of Shelah” (Luke 3:35). His appearance highlights the continuity between the covenant line of Genesis and the messianic line culminating in Jesus.

Theological Significance

1. Continuity of Promise

Each link between Noah and Abraham secures the transmission of God’s promise that the earth would be blessed through Shem’s line. Reu’s presence in Luke’s genealogy affirms that the divine purpose moved through real, historical persons, safeguarding the messianic hope.

2. Preservation of the Seed

After Babel’s judgment, humanity splintered into nations and tongues, yet the redemptive line remained intact. Reu’s generation shows God’s sovereign preservation amid cultural upheaval, foreshadowing the gathering of nations in Christ (Revelation 5:9-10).

3. Assurance of Scriptural Reliability

Luke’s genealogy corresponds with Genesis 11 and 1 Chronicles 1:25, demonstrating the unity of the Testaments. The harmony testifies to the trustworthy nature of divine revelation and encourages confidence in every portion of Scripture, including lists that may seem mundane.

Implications for Christology

By tracing Jesus back through Reu to Noah and ultimately to Adam (Luke 3:38), Luke presents Christ as the universal Savior. Reu plays a small but indispensable part in establishing Jesus’ solidarity with all humanity, fulfilling the angelic announcement of “good news that will cause great joy for all the people” (Luke 2:10).

Lessons for Faith and Ministry

• God values every generation. Unknown to the world, Reu still serves eternal purposes. Likewise, believers today may labor in obscurity yet remain essential in God’s unfolding plan.
• Faithfulness across centuries underscores the importance of transmitting the faith to children (Deuteronomy 6:6-7; 2 Timothy 1:5).
• Genealogies encourage pastors and teachers to proclaim the whole counsel of God, demonstrating how even brief notices deepen understanding of salvation history.
