Prophets
This page has links to various resources about the Old Testament Prophets.

How Raffael imagined Ezekiel's vision, but what was the point? (Raffaello Sanzio , via Wikimedia Commons)
Thinking about what a prophet was and how they spoke I used the title: “What does a prophet? What does it profit?” these are the slides from the talk. A key idea in this talk was my Prophets: three principles to unlock the code another that uses the same idea (but to addrerss a New Testament prophet) is: The teachings of Jesus the prophet you can get lots more 5 minute audio teaching about the Hebrew prophets and about particular prophetic texts using the menu above > OT > Prophets and choose a prophetic book.
Another good place to explore the nature and contents of biblical prophecy is the book of Amos. In this second part we looked at an example from Amos 5:18ff. and applied the “Three Cons” approach. The result was an uncomfortable word from God for us today. Here are the slides from that talk: Understanding the Prophets: Part Two: Amos 5:18ff. There are some podcasts that deal with the book of Amos here.
My commentary with also a huge amount of Bible Dictionary type material as well as pictures and background is here Amos: Hypertext Bible Commentary.
