Reu
A post-flood patriarch in the lineage of Shem, Reu was the son of Peleg and a direct ancestor of Abraham and Jesus Christ.
Reu was a significant post-diluvian patriarch mentioned in the genealogies of the Old and New Testaments. He lived during a transitional era of human history following the Great Flood and the scattering of nations at the Tower of Babel. According to the chronological records in the Book of Genesis, Reu represents the seventh generation from Shem, the son of Noah, placing him in a critical position within the line of the promised Seed.
While the biblical record provides specific chronological data regarding Reu’s lifespan and progeny, it offers little in the way of narrative action. His inclusion in both the Masoretic genealogies and the Lucan genealogy of Christ underscores his role as a biological and covenantal link between the early post-flood world and the eventual calling of Abraham. As a patriarch, he contributed to the repopulation of the earth during a period when human lifespans began a marked decline.
Background and Family
Reu was born into the Semitic line during the third century after the Great Flood. According to Genesis 11:18, his father was Peleg, a man whose name was associated with the division of the earth. The biblical record establishes Reu as part of a lineage that remained distinct amidst the emerging nations of the ancient Near East. His name, Reu (Hebrew: רְעוּ), is often interpreted by scholars to mean 'friend' or 'companion,' though the text does not explicitly provide an etymological origin for the name.
Reu was born when his father Peleg was 30 years old. This timeline places him in the heart of the post-Babel era, a time of migration and the establishment of new tribal boundaries. Like many of the patriarchs of this period, Reu’s family life involved the fathering of multiple children, though only his primary heir, Serug, is named in the sacred text.
Major Life Events
The life of Reu is defined primarily by the biblical chronogenealogies. The Genesis account notes that when Reu reached the age of 32, he became the father of Serug (Genesis 11:20). Following the birth of Serug, Reu lived for another 207 years, during which time he 'had other sons and daughters' (Genesis 11:21).
One of the most notable aspects of Reu’s life is his total lifespan of 239 years. While this would be considered extraordinary by modern standards, it represents a significant decrease compared to his ancestors. For instance, his great-great-grandfather Eber lived 464 years, while his descendant Abraham would live only 175 years. Reu’s life thus serves as a data point in the biblical narrative illustrating the gradual shortening of human life in the post-flood world. Beyond these vital statistics, the Bible records no specific travels, conflicts, or divine encounters involving Reu, suggesting his life was one of traditional patriarchal administration and family building.
Relationship to Other Biblical Figures
Reu’s primary significance lies in his place within the genealogical bridge connecting Noah to the nation of Israel. He is the son of Peleg and the father of Serug. His grandson was Nahor, and his great-grandson was Terah, the father of Abraham. Consequently, Reu is a direct forefather of the Hebrew people.
In the New Testament, Reu is listed in the genealogy of Jesus Christ recorded by Luke. Appearing as 'Ragau' (the Greek transliteration of his name), he is placed between Peleg and Serug in the lineage that traces Jesus’ ancestry back to Adam (Luke 3:35). This inclusion confirms his status not merely as a historical figure of the ancient past, but as a necessary link in the messianic line.
Spiritual Significance
While Reu is a 'silent' figure in the sense that no words of his are recorded, his spiritual significance is found in his preservation of the lineage of faith. The genealogies in Genesis 11 are intended to show how God preserved a specific family line—the line of Shem—through which the blessing of all nations would eventually come.
When Reu was 32 years old, he became the father of Serug. And after he had become the father of Serug, Reu lived 207 years and had other sons and daughters. (Genesis 11:20-21)
In the context of biblical theology, Reu represents the faithfulness of God in maintaining His promise despite the general rebellion of humanity at Babel. By surviving and fathering Serug, Reu ensured the continuity of the covenant line that would eventually produce the patriarch Abraham and, ultimately, the Messiah. His life reflects a period of quiet stability amidst a world undergoing massive geopolitical and linguistic shifts.
Spiritual Significance
The theological importance of Reu is rooted in the concept of the 'God of the living' and the continuity of the biblical covenant. As a link in the chain from Shem to Abraham, Reu is a witness to the transition from the primeval history of Genesis 1-11 to the patriarchal history that begins in Genesis 12. His inclusion in 1 Chronicles and the Gospel of Luke serves to validate the historical reality of the ancestry of Israel and the Davidic kings.
Furthermore, Reu’s specific lifespan provides a chronological marker for scholars attempting to reconstruct the timeline of the ancient world. His life bridges the gap between the immediate post-flood era and the rise of the great Mesopotamian civilizations. Though he performed no recorded miracles and delivered no prophecies, his existence was essential to the fulfillment of the protoevangelium—the promise that the seed of the woman would one day crush the head of the serpent.
