The Posuk says ([Shemot 25:8](http://mechon-mamre.org/p/pt/pt0225.htm#8)):

> 
> וְעָשׂוּ לִי מִקְדָּשׁ וְשָׁכַנְתִּי בְּתוֹכָם  
> 
>  And let them make Me a sanctuary ('Mikdash'), that I may dwell among them.
> 
> 
> 

I have two questions: first, this was the instructions for the Mishkan not the Beit HaMikdash; second, what's בְּתוֹכָם "among **them**"? Why the plural? Plain translation would indicate we are speaking of the Mishkan.
