Hebrew alphabet

"For reasons that remain obscure, in the case of the Palestinian Jews of Fustat, or Old Cairo—who worshipped in what would eventually become known as the Ben Ezra synagogue—the tradition of geniza was, it seems, extended to include the preservation of anything written in Hebrew letters, not only religious documents, and not just in the Hebrew language. Perhaps, as one scholar has proposed, "the very employment of the Hebrew script ... sanctified written material.""

"One way or another, the alphabet created a possibility that never existed before, namely of a society of mass, even universal, literacy. With only twenty-two symbols, it could be taught, in a relatively short time, to everyone. We see evidence of this at many places in Tanakh, the Hebrew Bible. Isaiah says "All your children shall be taught of the Lord and great shall be the peace of your children" (Isaiah 54:13), implying universal education."
