Clearly these reports do not have a common form, or structure, and apart from the visionary element itself they show little resemblance to each other in content or manner of working. Amos' vision reports are relatively poor in visual details. The story of the conflict between Priest and Prophet at Bethel is well told, sparing in its use of description, yet vivid in its impact. The theme of these verses is clearly the prophet and the word, and they tell a story. Other less characteristically prophetic genres are present too.
Most prophetic books contain a similar mixture of different types of material.
The word of the Lord to Israel by Malachi. An oracle concerning Nineveh. The book of the vision of Nahum of Elkosh. However Haggai's longer form begins to point in another direction. These hints suggest something more dramatic than a collection of sayings.
