"The Bible, King James version, Book 31: Obadiah" by Anonymous is a prophetic book written around 590 BCE. This shortest book in the Hebrew Bible delivers a divine judgment against Edom for betraying Judah during Jerusalem's destruction. The prophet Obadiah condemns Edom's pride and violence against "your brother Jacob," declaring total annihilation for those who stood aside while enemies plundered Jerusalem. The prophecy promises Israel's restoration and introduces the concept of "the Day of the Lord"—a phrase echoed throughout biblical literature.
