If the Davidic blood line was being so safely guarded by the Lord as the OT makes it out to be and the Law of Moses was instituted to preserve the blood line pure until the Savior should come? Then how in the world does a Gentile convert end up being the Great Grand Mother of Kind David and contaminating the blood line? http://www.online-bible.org.uk/ruth/ Hmmm... now Israelites can have Gentile blood lines thus complicating the DNA issue all the More!
