Why Should You Have New Testament Commentaries?

i went to go to jean green's commentary in the this is part of the be the baker exogetical commentary new testament series. i'm goingig to quote from green's commentary, which is another one i like, on jude. And he writes that woven into the fabric of juda are a number of references taken from jewish literature that did not become part of the jewish or christian canon. In verse six, jude refers to ann lic fall, which was an interpretive tradition based on genesis six one to four and elaborated extensively in first enoch six 12,. among other jewish texts. This is why you should have incident access to these commentaries
