I am trying to see if it would be a good investment for me to purchase Textual Criticism of the Hebrew Bible, 3rd Edition by Emmanuel Tov for the pre-pub price of $40, when I already have Lexham Methods series. Also, I see that I can get Paul Wegner's A Students Guide to Textual Criticism of the Bible for $12. Thoughts on the pros and cons of these resources when comparing them to each other? Thanks.
