Scribe B was a poor speller, and scribe A was not very much better; the best scribe was D. Metzger states: "scribe A had made some unusually serious mistakes". Scribes A and B more often used "nomina sacra" in contracted forms (ΠΝΕΥΜΑ contracted in all occurrences, ΚΥΡΙΟΣ contracted except in 2 occurrences), scribe D more often used forms uncontracted. D distinguished between sacral and nonsacral using of ΚΥΡΙΟΣ. His errors are the substitution of ΕΙ for Ι, and Ι for ΕΙ in medial positions, both equally common. Otherwise substitution of Ι for initial ΕΙ is unknown, and final ΕΙ is only replaced in word ΙΣΧΥΕΙ, confusing of Ε and ΑΙ is very rare. In the Book of Psalms this scribe has 35 times ΔΑΥΕΙΔ instead of ΔΑΥΙΔ, while scribe A normally uses an abbreviated form ΔΑΔ. Scribe A's was a "worse type of phonetic error". Confusion of Ε and ΑΙ occurs in all contexts. Milne and Skeat characterised scribe B as "careless and illiterate". The work of the original scribe is designated by the siglum א*.
