I Kings 9:26-28

King Solomon also built a fleet of ships at Ezion Geber, which is near Elath on the shore of the Red Sea, in the land of Edom. Then Hiram sent his servants with the fleet, seamen who knew the sea, to work with the servants of Solomon. And they went to Ophir, and acquired four hundred and twenty talents of gold from there, and brought it to King Solomon.
