The Jews shifted from Hebrew to Aramaic around 500 BCE - 100 BCE.
They started shifting back to Hebrew in the 1890's and today there are more than 6 million Hebrew speakers.
"Hebrew" is not a race, but a language that is a "cousin" of Aramaic, and can be traced to Old Canaanite.
It depends how Hellenized they were. Most Jews could converse in either Hebrew or Aramaic. (By the 300s BCE, Aramaic was starting to become dominant over Hebrew.) All Hellenized Jews could speak Koine Greek. Some of the Hellenized Jews were so enamored with Greek culture that they only knew how to speak Koine Greek and were no longer capable of speaking Semitic languages, but this was the minority.
The Gentiles of Palestine spoke Greek. The Jews of Palestine generally spoke Aramaic. However, the Jews of the diaspora mainly spoke Greek in their daily lives.
There is no Jewish Aramaic word for Bible. In ancient times, the Bible was not known by a single word: it was identified by it's various parts: the Torah, the Prophets, and the Sacred Writings. This came to be abbreviated by Jews in Europe as the acronym "Tanach" (תנ״ך) and the acronym "Tanach" is used in both Hebrew and Aramaic.
In ancient times, Jews spoke Hebrew. From about 250 BCE to about 200 CE, the main language of the Jews was Aramaic. Since then, Jews have migrated to almost every country in the world, and they speak the local languages of the regions they live in. Today, most Jews speak English as their native language or as a second language. Hebrew is the second most spoken language among Jews.
The Hebrew language, distinct from the Canaanite languages of its neighbours, seems to have developed in the tenth or ninth centuries BCE, and was probably an evolution of the Jerusalem dialect. This was the language of the early citizens of Judah.Around the end of the Babylonian Exile, the Persians adopted Aramaic as the lingua franca for its empire, so the Jews ceased to use Hebrew for day-to-day conversation, speaking Aramaic instead. After the Alexandrian conquests, the entire Near East adopted Greek as its language, except for the Jews, who continued to speak and write in Aramaic.
In the ancient days the Jews worship ped in the temple.
The Jews began doing this around the 1st or 2nd Centuries BCE.
The original language of the Hebrew people was Hebrew. This was related to Canaanite, Moabite and Aramaic. This reflected the regional origin of the Hebrews, who were later to become known as Jews. Following the establishment of the Persian Empire, Aramaic became the language common to the entire Near East. Aramaic was adopted by the Hebrews and remained the language of the Jews well into the post-biblical era.
"Bar" is an Aramaic word meaning "son". The Hebrew world for son is "ben". The reason for "Bar" in "Bar Mitzvah" is that ceremony came into existence when Jews still corresponded in Aramaic.
Jews have been speaking Hebrew continuously for about 4000 years, though Hebrew was only used for religious reasons for about 2000 years (c. 300 BCE to the 1880's). It was resurrected in the 1880's as a spoken language.
