While some people are interested in where the generations are different, my problem comes from where they are the same, to wit:

Boaz,
Obed,
Jesse,
David

Now Rahab is listed as the mother of Boaz. My understanding is that this is the same Rahab mentioned in the book of Joshua as the harlot of Jerico. If true, then both Matthew and Luke list only four generations covering the approximately 400 year period of the judges. There is no way (under normal circumstances) you get only four generations over that period of time unless you want to claim people were still regularly living 200-300 years during this time. 

In fact, my NKJV claims there were 11 generations during this time. So my question is: why would both Matthew and Luke fail to mention the 6-8 missing generations that must have occurred during the period of the judges? Small thing I know, but it has bugged me for years and I have never seen it addressed anywhere. TIA
