The sages ask why the Temple was built on Binyamin's land allotment.
Sifre explains that this was for 3 reasons*:
(1) He was the only brother who was born in the Holy Land
(2) He had no part in the sin of selling Joseph
(3) He had the zecut (privilege) of comforting Jacob in his old age
R' Hirsch sums it up nicely, Benyamin was "the one whose remembrance, entirely free from the slightest breath of any opposing thought, corresponded to the virtues that the site of the Temple was dedicated to foster."
* Another reason not mentioned by Sifre is that Benyamin never bowed to Esau (He wasn't born yet).
