There are 3 sections of a commentary to pay attention to:
Bible Commentary (other than New Interpreter’s Bible; see SBL Handbook of Style – Section 6.4.9):
For Bible commentaries other than the New Interpreter’s Bible, give the title of the book of the Bible that the commentary is about in italics followed by the name of the commentary series without italics (Interpretation, Westminster Bible Companion, Anchor Bible…).
An Entry in New Interpreter’s Bible (SBL Handbook of Style – Section 6.3.6):
A citation from the New Interpreter's Bible is treated like a dictionary/encyclopedia entry: your footnote and bibliographic citation should begin with the author of the entry instead of the editor of the New Interpreter's Bible. The author’s name can usually be found at the beginning of the entry. Then, place in quotation marks the name of the specific entry.
