[XeTeX] right justified paragraph in tabular or longtable

[Adam McCollum]

Dear list members,

I am putting together a document with several selections of text in  
Syriac on the right and an English translation on the left. Perhaps  
there is another way, but I've done this longtable. Since these text  
selections are several lines long, I've used p{7cm} for the alignment.  
It looks good except for the fact that I want the last line of the  
Syriac to be all the way to the right, while now it lingers far to the  
left. From what I understand, there is not an option of r and  
p{WIDTH}, but I assume there is another way to do what I need. Please  
see a minimal example attached.

Many thanks for any help.

With best wishes,

Adam McCollum, Ph.D.
