Cairo Geniza in the context of Jerusalem Talmud

Yevanic, also known as Judaeo-Greek, Romaniyot, Romaniote, and Yevanitika, is a Greek dialect formerly used by the Romaniotes and by the Constantinopolitan Karaites (in whose case the language is called Karaitika or Karaeo-Greek). The Romaniotes are a group of Greek Jews whose presence in the Levant is documented since the Byzantine period. Its linguistic lineage stems from the Jewish Koine spoken primarily by Hellenistic Jews throughout the region, and includes Hebrew and Aramaic elements. It was mutually intelligible with the Greek dialects of the Christian population. The Romaniotes used the Hebrew alphabet to write Greek and Yevanic texts. Judaeo-Greek has had in its history different spoken variants depending on different eras, geographical and sociocultural backgrounds. The oldest Modern Greek text was found in the Cairo Geniza and is actually a Jewish translation of the Book of Ecclesiastes (Kohelet).

Ben Naphtali (Hebrew: אַבּוּ עִמְרָן מֹשֶׁה בֶּן דָּוִד בֶּן נַפְתָּלִי, romanized: ʾAbbū ʿĪmrān, Mōše ben Dāwīḏ ben Nap̄tālī) was a rabbi and Masorete who flourished around 890-940 CE, probably in Tiberias. Of his life little is known.

His first name is in dispute. Some medieval authorities called him "Jacob"; two Chufut-Kale manuscripts have "Moses b. David"; a third contains his epigraph, which is incomplete, only "ben David ben Naphtali" remaining. His name is most likely Abu Imran, Moshe ben David ben Naphtali as preserved in Mishael ben Uzziel's 11th century treatise and in the Cairo Geniza fragment T-S K27.36 in the University Library at Cambridge.

The Babylonian vocalization, also known as Babylonian supralinear punctuation, or Babylonian pointing or Babylonian niqqud Hebrew: נִקּוּד בָּבְלִי‎) is a system of diacritics (niqqud) and vowel symbols assigned above the text and devised by the Masoretes of Babylon to add to the consonantal text of the Hebrew Bible to indicate the proper pronunciation of words (vowel quality), reflecting the Hebrew of Babylon. The Babylonian notation is no longer in use in any Jewish community, having been supplanted by the sublinear Tiberian vocalization. However, the Babylonian pronunciation as reflected in that notation appears to be the ancestor of that used by Yemenite Jews.

The Damascus Document is an ancient Hebrew text known from both the Cairo Geniza and the Dead Sea Scrolls. It is considered one of the foundational documents of the ancient Jewish community of Qumran.

The Damascus Document is a fragmentary text, no complete version of which survives. There have been attempts to reconstruct the original text from the various fragments. The medieval recension appears to have been shorter than the Qumran version, but where they overlap there is little divergence. The correct ordering of all the Qumran fragments is not certain.
