This work represents the first time that a major part of the masorah of the great Leningrad Codex, that of the Former Prophets, is being published with an English translation and commentary. The translation and commentary is preceded by an Introduction which deals with topics such as description of the importance of the Leningrad Codex, the Masorah and its development, the Masorah of the Leningrad Codex, and the relation of the Leningrad's Masorah to the accepted text of the Hebrew Bible. Every masoretic note in the Leningrad Codex that accompanies the text of the six books of the Former Prophets (Joshua, Judges, 1 Samuel, 2 Samuel,1 Kings, and 2 Kings) is transcribed, translated and annotated Every occurrence of each lemma is provided with its biblical references, and an indication is given as to where else in the ms. a note for any particular lemma may be found. Furthermore, and most originally, an attempt is made to suggest a reason for each note. The presentation employed in this work is user friendly so, for example, catchwords that occur in the Masoretic notes are arranged horizontally to correspond to their biblical references. This arrangement not only enables readers to immediately see the contexts where lemmas occur, but also to see where the lemmas are distributed in various sections of the Bible. Another aid for students is that all Hebrew references, other than in the ms., are given in a fully vocalized form.
