The Old Testament was originally written in Hebrew with a few passages in Aramaic. The New Testament was written in Greek - specifically Koine Greek, that is, the common Greek of the time.
Most of us rely on translations. People (generally teams of people) proficient in the original languages have done their very best to express the meaning in English. We can be very grateful but there is, of course, an advantage in being able to see what was written in those original languages. Often there are nuances that are hard to convey in the English.
We have basically three options:
Just stick with the English
Stick with the English but use tools that explain the original languages.
Learn one, or both, (or all three) of those original languages.
