Which book of the Bible details judgment against Edom?

The book that specifically details judgment against Edom is Obadiah. This short prophetic book is entirely focused on the prophecy concerning Edom, a nation descended from Esau that was viewed as an enemy of Israel. Obadiah predicts judgment against Edom for its violence against the people of Judah during the Babylonian invasion. It highlights themes of divine retribution and the notion that nations will ultimately be held accountable for their actions against God's people.

While other books, such as Amos and Hosea, address issues related to Israel and surrounding nations, they do not focus exclusively on Edom in the way that Obadiah does. Joel also addresses the themes of judgment and the Day of the Lord, but it does not specifically target Edom in the same manner as Obadiah. Thus, Obadiah stands out as the definitive source for understanding the judgment against Edom in the context of the Old Testament.
