In 1-2 Chronicles, there are a number of prophetic voices that proclaim Yhwh’s curse upon the king or Israel/Judah, usually foretelling the exile. Only 2 Chr 21:11-20 depicts the curse as being in written form, and only in this passage is the king explicitly cursed with illness. This curse story is also the only story of Elijah in Chronicles. In this paper, I explore the power of the genre of “curse letter” in Chronicles, in the biblical canon, and in scholarship.
