What Does the Bible Say about Ancestral Sin, Generational Spirits, and Curses?

This article considers this claim, starting with some observations on the text, and then other evidence adduced for the concept of generational spirits. The author goes on to speak about curses, defining what is meant by the term, and showing how certain biblical texts are misapplied in the discussion on curses.
