When I first started taking notes in my Bible, I mostly marked words and phrases that grabbed my eye. I then read somewhere, that you should never highlight something unless you write a note about it. I did not do this all the time, but I started underlining, highlighting and adding a few notes here and there. Often times, I added asterisks with footnotes.
