Here's a breakdown:
* Hebrew: The majority of the Hebrew Scriptures were written in Hebrew, including the Torah (the first five books), the Prophets, and the Writings.
* Aramaic: Some parts of the books of Daniel, Ezra, and Esther, along with a few other passages, are written in Aramaic. This is because Aramaic became a common language in the region during the Babylonian Exile and its aftermath.
So, while Hebrew is the dominant language of the Hebrew Scriptures, a small but significant portion is written in Aramaic.
