What About When Biblical Authors Quote From Non-canonical Sources?

This is a really interesting question because in the New Testament you have inspired authors quoting non-inspired, even pagan, literature to illustrate their various points. I don't think we would want to say that just because they quote from this literature that therefore that literature is historical or true. An illustration would be the magicians Jannes and Jambres that are referred to in 1 or 2 Timothy which were part of Jewish folklore and legend. These two became the prototype of evil persons in Jewish folklore, and there are different legends about them and what happened to them and how they met their demise and so forth. Just because Paul in Timothy refers to Jannes and Jambres doesn't mean that we should take them to be historical individuals that bore those proper names. So this would be an example of where the Scripture can be referring to a literary figure without committing itself to the historicity of that figure. It would be just as if I said, “Just as Robinson Crusoe had his man Friday to help him, so I have Michael Lepien to help me in my ministry.” Nobody would take that to mean that I am committing myself to the historicity of Robinson Crusoe. It's using a literary figure as an illustration, and I think that's what these New Testament authors are doing
