The original languages of the various books of the Bible were [[Biblical Hebrew|Hebrew]] (for Old Testament books) and [[Koine Greek]] (for New Testament books). A small amount of the [[book of Daniel]] was originally written in [[Aramaic]].
In the first few centuries after Christ the Bible was translated into a few other ancient languages (for example [[Latin]]) but it wasn't until the Protestant [[Reformation]] that widespread translation of the Bible into many languages (such as German and English) really began to occur.
