In BHS’s Masoretic apparatus, certain Masorah parva notes are marked “sub loco” in order to refer the reader to the corresponding commentary that was to be found in the third volume of Massorah Gedolah. Due to Weil’s passing, however, this commentary was never realized. This volume builds on Mynatt’s 1994 analysis and classification of the Pentateuch’s 297 sub loco notes by incorporating the Aleppo and Cairo Codices. Dost evaluates all 451 sub loco notes in the corpus of the Former Prophets, and evaluates Weil’s contribution by comparing Weil's revision of the Leningrad Codex’s Masorah against the Masorah of the Aleppo Codex.
