Other forms: Hebrews
Hebrew is the traditional language of the Jewish people, and it's also the Biblical name for their ancient ancestors. Today, Hebrew is the official language of Israel.
Biblical scholars use the term Hebrew for the descendants of the Old Testament's patriarchs, including Isaac and Abraham, an ancestral group also known as Israelites. The Hebrew language, as well as being spoken and written in Israel, is used for all religious texts, services, and prayers in Judaism. To wish someone peace in Hebrew, you can say "Shalom," and if you're congratulating them, say "Mazel tov!"
