Modern Greek speakers can NOT understand ancient Greek. And modern Hebrew is NOT mutually intelligible with Aramaic. The OP is correct and the two responses are nonsense. Also, in the 1500s when the Bible was translated to English, very few Europeans spoke Latin and if they did it was a very different Latin from the translations from the Roman era (pre 500 or so). Languages change over time and the Latin spoken by the aristocrats in the 1500s was very very different from the Latin spoken by the Romans.
