1 Kings 9:24-28

As soon as Pharaoh’s daughter came up from the city of David to her house which Solomon had built for her, then he built the Millo. Now three times in a year Solomon offered burnt offerings and peace offerings on the altar which he built to 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. They went to Ophir and took four hundred and twenty talents of gold from there, and brought it to King Solomon.
