This video introduces ‘ketiv qere’ – instances where the Masoretes noted the correct reading of a word in the margin of the text.  A ketiv qere occurs in Ruth 1:8.  This video is a little longer than normal.

For those who are interested in learning what the marginal notes mean in the BHS, Page Kelley has written a helpful book:
