This was a great semi-technical commentary on Genesis. I say semi-technical because the author avoids extended commentary on textual-critical issues, keeps things to a mostly English discussion, and also declines to move from historical-literary/theological message to contemporary application. Therefore, unless the reader is already familiar with Genesis and its theological message, and able to apply it already, they will need to supplement this commentary with something more praxis-focused.
But, in terms of its stated aims and scope, this commentary is fantastic. I especially appreciated Matthews' exegesis of the literary features of Genesis 1-11. He saves extended discussion about Germaine issues of science, creation-days, historical Adam, etc. for an "Excursus" section in the back, taking up about 110 pages of text. I skipped most of these, but read 489 pages of commentary.
I eagerly anticipate the revision of his 12-50 commentary, which should come out in the next couple of years by Holman.
