Ragau

Ragau is the Greek form of the Hebrew name Reu. UPDV uses the Hebrew form throughout, including in Luke's genealogy. The person is one of the post-flood patriarchs in the line of Shem: son of Peleg, father of Serug, and an ancestor of Jesus.

In the Genealogy of Shem

The Genesis genealogy gives the lifespan in two stages — years before the heir is born, then years afterwards. Reu's notice runs: "And Peleg lived thirty years, and begot Reu: and Peleg lived after he begot Reu two hundred and nine years, and begot sons and daughters. And Reu lived two and thirty years, and begot Serug: and Reu lived after he begot Serug two hundred and seven years, and begot sons and daughters" (Gen 11:18-21). The fixed points: Peleg begets him at thirty; he begets Serug at thirty-two; he lives two hundred and seven years more.

The Chronicler condenses the same genealogy to a list: "Eber, Peleg, Reu" (1 Chr 1:25). The order across the post-flood patriarchs is Eber → Peleg → Reu.

In the Genealogy of Jesus

Luke's reverse genealogy traces the line of Jesus back through these same patriarchs. The relevant link in UPDV reads: "the [son] of Serug, the [son] of Reu, the [son] of Peleg, the [son] of Eber, the [son] of Shelah" (Luke 3:35). The bracketed [son] marks UPDV's editorial supply where the Greek runs the genitive chain without a noun. The position is identical to the Genesis order, read in reverse.

The umbrella term Ragau is the form that comes through Greek transliteration; UPDV everywhere uses the Hebrew Reu, including in Luke 3:35.
