Twelve Minor Prophets (Nevi’im)
(Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, Malachi)
These are called Minor Prophets, not because they are not as important as the Major Prophets, but because they are short and all twelve fit on one scroll. Hosea through Malachi are for the most part collections of oracles in which the prophet spoke the "Word of the Lord" in order to encourage certain people to respond to God in a specific way. Prophecy is not about predicting the future, but influencing behavior. The prophets are more like the Ghost of Christmas Future in Charles Dick-ens' A Christmas Carol than Nostradamus. The book of Jonah is unique in that it is a short story rather than a collection of oracles. The message of Jonah is not found in the words of the character Jonah, but in what happens to him.
