The Minor Prophets, in alphabetical order, are Amos, Habakkuk, Haggai, Hosea, Joel, Jonah, Malachi, Micah, Nahum, Obadiah, Zechariah, and Zephaniah. Their books are considered minor since each is much shorter than the writings of Isaiah (sixty-six chapters), Jeremiah (fifty-two chapters), and Ezekiel (forty-eight chapters). If all of their writings were combined into a single book, it would be only two-thirds of the size of Isaiah.
The Book of Daniel, although it contains important prophecies from Daniel’s time to the end of the age and Christ’s return, is not included as part of the writings of the minor prophets. This is because Daniel wrote in Babylon during the Jews' 70-year exile.
