Obadiah

Obadiah is the shortest book of the Old Testament.  The book simply prophesies a coming judgment on Edom(descendants of Esau) who neighbored Judah to the south.  Obadiah speaks of deliverance for Judah and promsies that they will endure as a nation while all the other nations crumble.  Really Judah represents those who have come into the tribe of Judah by asking Jesus Christ into their heart.  They basically accept his wedding proposal and thus they become a part of the family of Judah.  All people who are not a part of Judah will indeed be ju8dged accordingly.
