Since there are so many translations, does it mean there are many Bibles instead of just one?  No. 

The various translations are all translations from the Greek, Aramaic and Hebrew languages used for the original text of the Bible.  They are considered the Word of God. 

In contrast is Islam’s view of the Qur’an.  The Arabic Qur’an is held to be the only authentic version.  Other translations are viewed as merely conveying the meaning or interpretation 
of the Qur’an and they are not deserving of being called “the Qur’an.”

There is a Greek translation of the Old Testament called the Septuagint, which was in use alongside the Hebrew Old Testament at the time of Jesus.  Jesus never referred to this translation, but it is believed that He quoted from it.  Since he grew up in Northern Palestine he had a strong Greek speaking influence and spoke Aramaic.  He also knew Hebrew and could read it fluently.  The Septuagint Version which was completed in 180 BC was a translation of the entire Old Testament into Greek.
