We don’t know who wrote Hebrews, but it surely wasn’t Paul even though some still contend he did. Anyway, no major commentary today argues that Paul wrote it, and these are the major ones I turn to … and, once again, there is an abundance of really fine commentaries. No one can suggest we are in serious need of a good commentary on Hebrews. I’m sure I’ve missed some good ones, so speak up if you think I have.
I begin with Harold Attridge, in part because I worked through it carefully with a class years back when it first appeared: Hebrews: A Commentary on the Epistle to the Hebrews (Hermeneia: A Critical and Historical Commentary on the Bible)
Then Craig Koester’s more recent Anchor Bible: Hebrews: A New Translation With Introduction and Commentary
Then Paul Ellingworth’s thoroughgoing commentary in the NIGTC series: The Epistle to the Hebrews: A Commentary on the Greek Text (New International Greek Testament Commentary)
And I check Luke Timothy Johnson: Hebrews: A Commentary (New Testament Library)
