Abdiou is a form of the name Obadiah used in the Greek Old Testament, also spelled Ἀβδίας (Abdias). The name Obadiah, derived from Hebrew, means 'servant or slave of Yah,' referring to a biblical prophet traditionally attributed as the author of the Book of Obadiah. The book is dated to shortly after the fall of Jerusalem in 587 BC and is considered to have been shaped by conflicts between Yehud and the Edomites in the fifth and fourth centuries BCE.
