The Aramaic alphabet is ancestral to what alphabet known variously by scholars as the Jewish script?
Aramaic language Aramaic (אַרָמָיָא "Arāmāyā", Syriac: ܐܪܡܝܐ‎ , Arabic: آرامية‎ ‎ ) is a language or group of languages belonging to the Semitic subfamily of the Afroasiatic language family. More specifically, it is part of the Northwest Semitic group, which also includes the Canaanite languages such as Hebrew and Phoenician. The Aramaic alphabet was widely adopted for other languages and is ancestral to the Hebrew, Syriac and Arabic alphabets.
Mosaic authorship Mosaic authorship is the Jewish and Christian tradition that Moses was the author of the Torah, the first five books of the Hebrew Bible/Old Testament. The books do not name any author, as authorship was not considered important by the society that produced them, and it was only after Jews came into intense contact with author-centric Hellenistic culture in the late Second Temple period that the rabbis began to find authors for their scriptures. The tradition probably began with the law-code of Deuteronomy, and was then gradually extended until Moses, as the central character, came to be regarded not just as the mediator of law but as author of both laws and narrative.
