The Lord's Prayer in Greek

Here is The Lord's Prayer, read in modern Greek pronunciation with a literal English translation below the Greek text.  The Koine (Common) Greek pronunciation would, of course, not be exactly the same as modern Greek.

Dr. James Blanton at the Southern Baptist Theological Seminary in Louisville, Kentucky (USA) demonstrated that the Koine was pronounced more similarly to modern Greek than to the Erasmian pronunciation which many academics use.  Dr. Blanton based this demonstration on misspellings in hand-copied Greek texts from the first few Christian centuries.

Since the texts were copied by men transcribing what was being read aloud from a master text, misspellings of words showed how many of the vowels had similar sounds and could be mistaken for one another by inexperienced scribes.  Since the pronunciation of some words was known for certain, the pronunciations of other words could be deduced.
