How did G-d want to consume the jews if King David was to come from the Tribe of Judah ?

Question:

In last week’s parsha g-d told moshe he wanted to wipe out all the jews and make the Jewish nation come from moshe how is it possible g-d took 70 years from Adam to give to David and David is supposed to come from the dynasty of yehuda so how is it possible that God would wipe out the Jewish nation? 

Answer:

A beautiful question to think about!

But the answer to this is clear: The Creator knows in advance the hidden and watches and looks to the end of the generations, And as the ‘ramban’ says (Chapter 5 of teshuva) and so on, the Creator knew that Moses would implore prayer, and on this basis he took from adam the years and gave it to King David, and what he said, “Bar from me and I will destroy them”, he means, that this is what was supposed to be punished to them, but really the Creator had no intention of inciting the Jewish nation but here alluded to Moses who plucked in prayer and as Rashi says, And he knew he would do so.
