Commentaries recommended for preachers include the following, There are a number of good commentaries on Matthew's Gospel. Easily the best is R.T.France, Matthew, in the New International Commentary series (not to be confused with his earlier work in the Tyndale Commentaries which is now redundant). If you have this you do not need much more for basic exegesis. William Hendriksen's work is warm and more inspirational than most and basically reliable; I recommend it.
But you might want to add one or two more to your collection. There is Craig Blomberg in the New American series, Don Carson in the Expositor's Bible Commentary, Donald Hagner in the Word Commentary, Keener. David Turner is another in the Baker series.
I see that R.C.Sproul has recently produced a book on Matthew's Gospel; I have not yet used it.
Rudolf Schnackenburg is a Catholic commentator; it is not needed but you might want to know about it. Eduard Schweitzer's commentary seems to be no longer mentioned by anyone; it can be left aside.
Among the works which are more inspirational and might help preachers I must mention Ryle and Spurgeon. They are both very simple but should not be despised. I have not used Boice but imagine he would be good.
Lenski is perhaps not needed nowadays, although I value his comments on the harmonising
the gospel narratives, which he likes to do. I always found Morris's commentary disappointing. He was a capable scholar but his commentaries are not very inspiring.
McNeile is an older work, and contains the Greek text. I like reading him but I suppose he is hardly needed if you have the basic works.
The old Scotch writer David Dickson produced a worthy book on Matthew. It is available from Banner of Truth.
I have enjoyed reading Exell's Matthew in the old Biblical Illustrator volume. From Kenya I was never able to download the free version on Internet but others might have more success.
Allison & Davies (ICC) are generally destructive in their views but they give you lots of information about what people think of Matthew, section-by-section. Gundry is known for
his view that Matthew is 'midrash' (i.e. not always accurate historically). Nolland (Word Commentary) is of little value to preachers. Frederick Dale Brunner I have never used. William Barclay is loved by many but I find him infuriating in his mixture of destructive scepticism and devout language. He's a good writer, I admit.
Special works on the Lord's Prayer and the Sermon on the Mount I'll come back to another time.
