A polyglot Bible is a multilingual Bible in which the different texts are displayed in parallel columns. A massive undertaking for the Bible Society, the Biblia Polyglotta features the Old Testament in five languages: Hebrew/Aramaic, Greek, Latin, English and Spanish; and the New Testament in four languages: Greek, Latin, English and Spanish.This same kind of Bible - though obviously not this one - is referred to as a "Parallel Bible" (Online Parallel Bible) in which different translations are placed side-by-side. This can be useful for study as you can see how different translators have interpreted the same original word or phrase.
Of course, if you DO use one of these, be sure to only study the NIV for Quiz Team, as other translations are not used in our questions.
