Obadiah

In the ninth century B.C., Obadiah prophesied about the destruction of Edom, the descendants of Esau.  Verse 3 indicates that Edom was guilty of pride, and this sin is what brought her destruction.  The pride of the Edomites had deceived them into thinking that they were invincible, and that they didn't need God, but God would prove them wrong.

Obadiah also predicted the eternal reign of Israel.  Israel would be restored, and God would reign over His Kingdom, which would include the land of Israel as well as Edom.
