honest broker

"A broker expects to reap a benefit, a commission or fee, from negotiating a deal between or among other parties... The word broker stems from the Spanish alboroque, a ceremonial gift at the resolution of a business deal, which in turn is from the Arabic baraka, divine blessing.  Barack Obama's first name comes (by way of his father, same name) from that word."
