"Hebrew was born around the 12th century BC. It’s the language of the Bible; Jesus knew Hebrew. But a few decades after Jesus’ death, Jews were exiled from the Holy Land, and they adopted different languages.
“Hebrew for 1,700 years wasn’t spoken by anyone,” Birnbaum said. “Some people call it a dead language. But if it was dead, it was a very lively corpse.”
It really wasn’t dead at all. Jews wrote their literature and liturgy in Hebrew, and recited prayers in Hebrew, as they do to this day. In the late 19th century, waves of Jews moved to the Holy Land, and revived Hebrew as a spoken language."
