About 586 B.C., Babylon took Judah into exile and as neighbor Edom helped Babylon and took away Judah's southern territory, God sent His servant Obadiah to explain the situation to His people. Obadiah has two messages: God know and will judge the sins of His people's enemies, and the day of the Lord will bring deliverance for God's people. Obadiah shows God's justice, sovereignty, and grace amid disaster. The salvation of God's people and the destruction of Edom were both prohesied in the book of Obadiah verses 17+18. The fact that Edom no longer exists, and that the Israelites were again restored to their homeland, prove the accurate fulfillment of this prophecy.(Jeremiah 25:15-17, 21, 27-29; 49:7-22 and Ezekiel 25:12-14; 35:1-15 joined Obadiah in his prophecy about Edom's destruction).
