I am preaching through Matthew and have extensively used a number of commentaries. This is an enjoyable read. The two volumns are worth the money but they are not techincal at all. Since these are Boice's sermons, there are sermon ideas with the text but I look to several commentaries first in sermon prep. They are excellent hidden nuggets in this text (Sermon on the Mount) as well as Boice's 2 Volumns on Matthew.
