This is the third, revised edition of the standard commentary on the Genesis Apocryphon. This edition has integrated new textual findings, in particular two columns of the text previously considered to be too fragmentary for inclusion. The commentary also evaluates recent scholarly discussion on virtually every part of the text. This edition also presents an updated reference grammar of the Aramaic of the Genesis Apocryphon and a complete glossary. In this respect the book can also serve as a solid introduction to the study of the Aramaic of Qumran.
