The Book of Obadiah is found in both the Hebrew Bible and the Old Testament of the Christian Bible, where it is the shortest book, only one chapter long. Its authorship is generally attributed to a person named Obadiah, which means “servant (or worshipper) of the Lord”. Obadiah is classified as a "minor prophet" in the Christian Bible due to the brevity of the writing (only 21 verses) and the content (prophetic material). An Old Testament prophet was [professedly] not only a person who was given divine insight into future events, but a person whom the Lord used to declare his word.
