This is the fourth and last volume of parabiblical texts from Qumran Cave 4 and reveals once again the interest in biblical themes characteristic of Second Temple period Judaism, exhibited in many of the Qumran compositions. It is devoted to a small group of texts showing the rewriting, in different ways, of two biblical prophetic books, Jeremiah and Ezekiel. Because of their fragmentary nature it is not clear how many copies or even compositions are reflected by the preserved fragments: at least five manuscripts of one composition of Pseudo-Ezekiel, and seven manuscripts of two different compositions of the Apocryphon of Jeremiah.
