I'm looking for Targum Neofiti online in the original Hebrew/Aramaic lettering. Does anyone know where I can find it?
Yes, it is available online at the Hebrew Union College's Jewish Institute of Religion in their Comprehensive Aramaic Project. Just click on "Search the CAL textual databases" in the left column. Then go to "Targum Studies Module," then "Browse a Single Targum," and you will see Targum Neofiti. Note that every word is tagged so you can click on it for a lexical analysis. You may need to download special fonts.
The scanned manuscript itself is online at the Vatican Digital Library (Biblioteca Apostolica Vaticana).
