The golden wedge of Ophir - what is it?

King James Bible
I will make a man more precious than fine gold; even a man than the golden wedge of Ophir.


Wesley's Notes
13:12 More precious - The city and nation shall be so depopulated.

Ophir (pronounced) oh-feer, is a place known to have much gold.  Ophir is also the name of a descendant of Noah.  Perhaps he founded the land of Ophir.
