Benjamin Outhwaite examines how deviations from the standard Tiberian tradition found in ‘Common Bibles’ from the Cairo Genizah reveal the way Biblical Hebrew was pronounced by those who produced the manuscripts.

It illustrates numerous deviations in notation from the standard conventions of Tiberian vocalisation and also many features that reflect a pronunciation different from that of the standard Tiberian tradition.
