Jewish Aramaic was a Western Aramaic language spoken by the Jews during the Classic Era in Judea and the Levant, specifically in Hasmonean, Herodian and Roman Judaea and adjacent lands in the late first millennium BCE, and later in Syria Palaestina and Palaestina Secunda in the early first millennium CE. This language is sometimes called Galilean Aramaic, although that term more specifically refers to its Galilean dialect.
The most notable text in the Jewish Western Aramaic corpus is the Jerusalem Talmud, which is still studied in Jewish religious schools and academically, although not as widely as the Babylonian Talmud, most of which is written in Jewish Babylonian Aramaic. There are some older texts in Jewish Western Aramaic, notably the Megillat Taanit: the Babylonian Talmud contains occasional quotations from these. Dead Sea Scroll 4Q246, found in Qumran, is written in this language as well.
