If you are interested in the Language Problem as it applies to the Gospels, then 'Did Jesus Speak Greek?' will be a fine addition to your library. It is a good introduction to the issues and identifies some of the main protagonists of three rival positions favouring Aramaic, Hebrew, or Greek. It is weighted in favour of the position that Jesus and his disciples spoke and taught in Greek, but provides a helpful bibliography for those who wish to explore other positions.

I have found 'Invitation to the Septuagint' to be insightful and comprehensive. I got Logos to read it to me all the way through, and have cited it more than once in my present research. Thank you for a job well done.
