Thanx Muh-law'chi. Is this the one they found in that Nag Hagami place?
Jerome (340-420 AD) tells us
"Matthew,30 also called Levi, apostle and aforetimes publican, composed a gospel of Messiah at first published in Judea in Hebrew31 for the sake of those of the circumcision who believed, but this was afterwards translated into Greek though by what author is uncertain.
Gospel of the Hebrews (Egypt, mid 2nd century CE) All that survives to us from the 'Gospel of the Hebrews' are several quotations made by Clement, Origen, Jerome, and Cyril of Jerusalem. Jerome took a lively interest in this book, an Aramaic copy of which he found in the famous library at Caesarea in Palestine. More than once he tells us (and with great pride) that he made translations of it into Greek and Latin. Unfortunately, these translations have been lost.
