Indeed. there is a whole section in the Old Testament which does not square with its dominant ideas. The Proverbs, to my mind the best part of the Bible, represents a non-Mosaic tradition. In its spirit, it is very different from the Pentateuch and the Prophets; its ethics is high; it represents a very different spiritual tradition, the tradition of Self-knowledge. Its teaching is mostly, anonymous; it has also a woman teacher... rather an exception in the Bible...
