1 Kings 9:25-29

Now three times a year Solomon offered burnt offerings and peace offerings on the altar which he had built for the Lord, burning incense with them on the altar which was before the Lord. So he finished the house.

King Solomon also built a fleet of ships in Ezion-geber, which is near Eloth on the shore of the Red Sea, in the land of Edom.

And Hiram sent his servants with the fleet, sailors who knew the sea, along with the servants of Solomon.

And they went to Ophir and received 420 talents of gold from there, and brought it to King Solomon.
