Carol, Semites of different religions have lived in the area known as Palestine for thousands of years. Many languages have evolved and then been superceded in and around this area, including various dialects of Aramaic (spoken by Jesus), Canaanite languages, the Moabite language, Hebrew, and Phoenician languages. By the time Jesus was born, the Jews used either the Jewish dialectical version of Aramaic or Greek for most of their writings and in daily life.

The Arabic and Amharic languages emerged in the mid-fourth century C.E. Arabic completely displaced its predecessors after only a few hundred years in the area where Arabic speakers had become politically dominant. Thus all the South Arabian languages and Aramaic, in all its varied dialectical forms, became to all intents and purposes "dead" languages very soon after the emergence of Islam in the seventh century C.E.

They have gone through a painful process in Northern Ireland, a lot of which comprised getting angry, devastated Protestants and Catholics to listen to each other. Change has happened slowly and carefully. I hope it can happen in Israel and Palestine too.
