Not naming your sources is considered plagiarism and is also against the rules (or used to be).I posted Ellicott's commentary because he said it much better than I ever could. Would you prefer me to write something with the same meaning but less clear and thorough? I know I wouldn't. Let us not be as the scribes and pharisees of Jesus' time who were petty/unpleasable as Christ spoke of in chapter 11 of Matthew comparing them to children in the marketplace.
