Σαδώκ is the Greek rendering of the Hebrew name צָדוֹק (Tsadok), meaning 'righteous.' This name appears in Matthew's genealogy of Jesus, referring to one of the post-exilic ancestors in the line from David to Christ. The name Zadok was famous in Israel's history—the high priest who remained loyal to David and Solomon—and continued to be used among Jewish families as a marker of priestly heritage and righteousness. Matthew's inclusion emphasizes Jesus' legitimate descent through Israel's honored lineages.
