Boanerges

It is generally agreed by historians that Jesus and his disciples primarily spoke Aramaic (Jewish Palestinian Aramaic), the common language of Judea in the first century AD, most likely a Galilean dialect distinguishable from that of Jerusalem. The towns of Nazareth and Capernaum in Galilee, where Jesus spent most of his time, were Aramaic-speaking communities.

Aramaic was the common language of the Eastern Mediterranean during and after the Neo-Assyrian, Neo-Babylonian, and Achaemenid Empires (722–330 BC) and remained a common language of the region in the first century AD. In spite of the increasing importance of Greek, the use of Aramaic was also expanding, and it would eventually be dominant among Jews both in the Holy Land and elsewhere in the Middle East around 200 AD and would remain so until the Islamic conquests in the seventh century.

According to Dead Sea Scrolls archaeologist Yigael Yadin, Aramaic was the language of Hebrews until Simon Bar Kokhba's revolt (132 AD to 135 AD). Yadin noticed the shift from Aramaic to Hebrew in the documents he studied, which had been written during the time of the Bar Kokhba revolt. In his book, Bar Kokhba: The rediscovery of the legendary hero of the last Jewish Revolt Against Imperial Rome, Yigael Yadin notes, "It is interesting that the earlier documents are written in Aramaic while the later ones are in Hebrew. Possibly the change was made by a special decree of Bar Kokhba who wanted to restore Hebrew as the official language of the state".
