Obadiah
Obadiah (pronounced , Hebrew: עבדיה ʿOvadyah or עבדיהו ʿOvadyahu, or in Modern Hebrew Ovadyah) is a Biblical theophorical name, meaning "servant of God" or "worshipper of Yah." The form of Obadiah's name used in the Septuagint is Obdios; in Latin it is Abdias. The Bishops' Bible has it as Abdi.
Prophet Obadiah
"The political situation implied in the prophecy points to a time after the Exile, probably in the mid-fifth century B.C. No value can be attributed to traditions identifying this prophet with King Ahab's steward (... so Babylonian Talmud, Sanhedrin 39b) or with King Ahaziah's captain (... so Pseudo-Epiphanius...)." The Interpreters' Bible
Rabbinic tradition
According to the Talmud, Obadiah is said to have been a convert to Judaism from Edom, a descendant of Eliphaz, the friend of Job. He is identified with the Obadiah who was the servant of Ahab, and it is said that he was chosen to prophesy against Edom because he was himself an Edomite. Moreover, having lived with two such godless persons as Ahab and Jezebel without learning to act as they did, he seemed the most suitable person to prophesy against Esau (Edom).
