This is another key book. Here pride of place goes to Harold Hoehner's commentary. It is thorough in its handling of the Greek text. The NIV Application commentary by Klyne Snodgrass is also quite good, the best for lay people. Less conservative on authorship but still full of good observations is Andrew Lincoln's handling of the book in the Word series. Other technical commentaries are by Ernest Best and Markus Barth.
