Why NOT Christ Lineage through Joesph's boodline, Instead of Judah's

OK, I recently, well a while back started a thread on this to which I got A LOT of "talking in circles", answers. Here ie the deal:A few months back our Pastor asked this question: "Here is your "homework: Why did not the lineage of Jesus Christ go through Jacob's son Joesph, AND why did it go through Judah's boodline? I need specific answers to both pqrts of the question"Well after searching/looking/asking/crossreferencing/ et.al. I STILL cannot come up with BOTH parts' answers.So What am I asking for...?I need someone to explain specifics on why Judah. AND WHY NOT, Joesph.I know that your thinking: Is it in the Bible? The answer is YES, our pastor said It IS IN There.SO please give me book:chapter:verses, and also, Please explain BOTH parts to me, PLEASE???I have really searched to no avail, Can someone PLEASE help me.May God Bless and Keep you Throughout the Holiday season!!!!

Thanks, A LOT!!!!!

OK:I as the starter of this thread I would like to say something:WOW!!! Thanks to all who have replied/discussed/spoken of/about/ toyed with etc, the subject.My Purpose: WHY DID the Lineage NOT GO THROUGH Joseph instead of Judah??WHY? There is specifically somewhere in the Bible that tells Why Joseph could not be the bloodline?Any thoughts, OR did I miss that somwhere in the LONG thread, I have read so much in the last hour I think I either totally missed it or it did not get answered...???Help please.
