When it comes to the New Testament, things get a bit more interesting. It was written mostly in Koine Greek, which was the language of the common people in the Mediterranean region at that time. Yep, you read that right - Greek! Who knew that the language of philosophers and mathematicians would become the language of the Bible?
The use of Greek in the New Testament was a deliberate choice, as it allowed the message to reach a wider audience. It's like the authors were saying, "Hey, we want everyone to understand this, not just the fancy-pants Hebrew scholars!" And, fun fact, the Greek used in the New Testament is still studied by scholars today, and it's considered one of the most accurate forms of ancient Greek.
Now, you might be wondering, what about Aramaic? Well, it's like the special guest star of the Bible - it makes appearances in both the Old and New Testaments. Jesus himself spoke Aramaic, and some of his famous phrases, like "Abba" (meaning "father"), are still used in Christian prayers today. Who knew that Aramaic would become the cool kid of ancient languages?
