If you are interested in learning Biblical Greek, and you want to know how it sounded at the time of Jesus, you will probably enjoy these materials tremendously. Using drawings and audio, Buth employs a method commonly found in books on modern languages. It’s a great way to internalize the language!
Take a look at the following nine minute video by James Tauber to see a very innovative use of currently developing technology to support acquiring New Testament Greek. He posted this video to Youtube about two years ago. I hope significant progress has been made on the project since then.
