The prophetic books in the bible , are all about the prophets warning the Jewish people that they would have to repent or be punished. I also talks of the coming of the lord Jesus Christ the first time in Isaiah.
(Major) Isaiah Jeremiah (Lamentations is more poetical but is written by the prophet Daniel) Ezekial Daniel.........(Minor) Hosea Joel Amos Obadiah Jonah Micah Nahum Habakakuk Zechariah Haggai...
All biblical books are prophetic to one degree or another, but the shortest in the Old Testament is Obadiah with 21 verses, and the next-shortest would be Jude (25 verses) in the New Testament.
