The
Logos freebie this month is a super good one. If you don't already have a Logos account, my opinion is that it's worth signing up just for this book.
A Critical and Exegetical Commentary on the Pastoral Epistles by I. Howard Marshall and Philip H. Towner.
If you're willing to spend another $4.98 ($1.99 for the first, $2.99 for the second), you can also get
A Critical and Exegetical Commentary on the Acts of the Apostles, Volumes
One and
Two by C. K. Barrett.
These are volumes of the
International Critical Commentary series, which is similar to the
Anchor Yale Bible series. If you don't know what the "Pastoral Epistles" are, the free volume covers Titus, First Timothy and Second Timothy.
If you want to know the scholars' opinions about the theology and textual traditions of the various books of the Bible, you can't do better than this series and, to borrow a phrase that normally doesn't come up in biblical discussions, "the first one's free." I can't recommend these books highly enough.
The
entire series is also on sale for $1,121.68 (regular price $1929.99), in case you like it so much you just need to have all of them.
Keep in mind that Logos books can't be liberated by Alf's tools and require
free Logos software to be read offline. They can, however, be read anytime online at
biblia.com if you login using your Logos account credentials.
The volumes are updated periodically so that they reflect the latest scholarship, but it's been around long enough that some of the original volumes have entered the public domain. Google Books, in their attempt to remove duplicate books from their collection, has inadvertently removed some of the books, but the
Internet Archive has, as far as I can tell, every volume for which the copyright has expired. Note that every time a volume is updated, it's completely redone from scratch by a new author, so the old ones are worth reading, too.
The original two volumes on Acts at the Internet Archive:
Volume 1 and
Volume 2.
The original volume on the Pastorals was published in 1924, so missed being in the US public domain by about a year (assuming the copyright was renewed, which I assume, but don't actually know either way). The author died in 1933, though, so it's public domain in life+70 countries (i.e. just about everywhere except the U.S.). It's at the Internet Archive
here.
