Several ancient sources attest to a gospel by the disciple Matthew as having been written in Aramaic, but with Hebrew letters.
Also, Aramaic is not the dead language people suppose. It persists today, among Syrian and Lebanese Christians. As I understand it, Hebrew is the language of the Jews (Judeans), whereas Aramaic was a language of the Gallileans and Samaritans. In the few places where Jesus’ language is retained in the gospels, it is Aramaic, yet Jesus certainly knew Hebrew as a rabbi who read scripture in the synagogue.
I believe the Samaritans spoke Hebrew.
