Afterlife 15: The Letter of Jeremiah

I'm back with Gil Kidron of A Podcast of Biblical Proportions.
In its 29th chapter, the book of Jeremiah contains a letter that the prophet wrote to the exiles in Babylonia. There is another letter of Jeremiah to the exiles, a very short work. In the Orthodox tradition, this is a separate book all to itself. In the Catholic canon, it is a chapter in the book of Baruch. Thanks to Martin Luther, the Protestants don't have it in any form.
In this episode, Gil and I investigate the letter. Who wrote it, when, and why.
