In the context of the recent discussion of kri u'ktiv I would like to call attention to the audio lectures of my friend and colleague Rabbi Adam Mintz that are available online at [
www.rabbimintz.com]
His lecture on Establishing The Correct Text Of The Torah: Is Our Torah Text The Same Text That Was Given To Moshe? [
www.rabbimintz.com] discusses kri u'ktiv together with other challenges in the Biblical text. Aside from the audio, each lecture includes source material available as a pdf file.
