The New York Times has published an article on the past and future of the Hebrew language. This paragraph is important:
Hebrew was never actually dead. It was more like an unborn child, according to Ariel Hirschfeld, a Hebrew literature lecturer at the Hebrew University of Jerusalem, slowly developing over the centuries as the language of Jewish letters and prayer. Educated Jews would read the weekly Torah portion in Hebrew, while sages from Prague to Baghdad would correspond on religious questions in their only common tongue.
Hebrew is not just the language of Zionism; it is the language of the Jews and has been since the time of the Bible. This is why its future is just as important as its past.
