What is "major prophet"

n. Any of the five longer prophetic books in the Old Testament: Isaiah, Jeremiah, Lamentations, Ezekiel, or Daniel.

The Major Prophets is a grouping of books in the Christian Old Testament. These books are centred on a prophet, traditionally regarded as the author of the respective book. The term "major" refers to their length, in distinction to the Twelve Minor Prophets, whose books are much shorter and grouped together as a single book in the Hebrew Bible.

The books, in order of their occurrence in the Christian Old Testament, are:

• Book of Isaiah
• Book of Jeremiah
  • Book of Lamentations (in the Ketuvim (Writings) section of the Tanakh)
  • Book of Baruch (not in Protestant Bibles)
    • Letter of Jeremiah (Chapter 6 of Baruch in most Catholic Bibles, its own book in Eastern Orthodox Bibles)
• Book of Ezekiel
• Book of Daniel (in the Ketuvim of the Hebrew Bible).

The Hebrew Bible includes the Books of Isaiah, Jeremiah and Ezekiel among the Nevi'im (Prophets) but places Lamentations and Daniel among the Ketuvim (Writings). Baruch (including the Letter of Jeremiah) is not part of the Hebrew Bible.
