Hebrew is a language that is native to Israel. Historically, it was spoken by the Israelites and their descendants, the Judeans, and Samaritans.
There are several forms of the Hebrew language, including pre-modern Hebrew, which is used for prayer and study in Jewish communities, and modern Hebrew, which is the official language of Israel.
Hebrew is often spoken by people who practice Judaism. However, they are not the same thing. Many non-Jewish people also speak Hebrew!
