ANSWER: HEBREW, ARAMAIC, GREEK - Let's start by saying that the instructions of God started with the Hebrews. Being the only language, they understood, scriptures were therefore undertaken in HEBREW language and almost all of the old testament was written in Hebrew language,
Howeveer, at some point, the language ARAMAI was beginning to gain extensive ground amongst the Jews and thereby some scriptures were written in ARAMAI. To be precise - Ezra, Daniel and Jerimiah.
Towards the turn of the century as one might say, many scholars amongst the Hebrews spoke GREEK. Many Jews could no longer relate with Hebrew language. Greek was like the modern day language. Hence, the NEW TESTAMENT was written in GREEK.
We might therefore say Hebrew, Aramaic - old testament. Greek New Testament.
