What language(s) did Jesus speak?
Aramaic is still spoken by scattered communities of Jews, Mandaeans and some Christians. Small groups of people still speak Aramaic in different parts of the Middle East. … Today, between 500.000 and 850.000 people speak Aramaic languages.
It is generally agreed by historians that Jesus and his disciples primarily spoke Aramaic, the common language of Judea in the first century AD, most likely a Galilean dialect distinguishable from that of Jerusalem. The villages of Nazareth and Capernaum in Galilee, where Jesus spent most of his time, were Aramaic-speaking communities. It is also likely that Jesus knew enough Koine Greek to converse with those not native to Judea, and it is also possible that Jesus knew some Hebrew for religious purposes.
