Leningrad Codex

"Samuel b. Jacob, who copied the Leningrad Codex, declares expressly that he had copied the Codex from several correct and clear codices which had been prepared by the master Aaron b. Moses b. Asher."

"There is no need to defend the use of the Leningrad Codex B19A (L) as the basis for an edition of the Hebrew Bible, whatever one may think of its relationship to the Ben Asher text. P. Kahle's own views on the matter may be consulted in his book The Cairo Geniza (Oxford, 1959, 2nd edition). In any event, L is still "the oldest dated manuscript of the complete Hebrew Bible.""

"Samuel ben Jacob wrote and pointed and provided with Masora this codex of the Holy Scriptures from the corrected and annotated books prepared by Aaron ben Moses ben Asher the teacher, may his rest be in the Garden of Eden!"

"A certain Samuel b. Jacob copied this Standard Codex of Ben-Asher for Meborach Ibn Osdad. This very important copy is now in the Imperial Public Library at St. Petersburg."

"It comprises the single most complete source of all of the Bible books which is closest to the Ben Asher tradition."
