1 Kings 9:24-28

But Pharaoh’s daughter came up out of the city of David unto her house which Solomon had built for her: then did he build Millo. And three times in a year did Solomon offer burnt-offerings and peace-offerings upon the altar which he built unto Jehovah, burning incense therewith, upon the altar that was before Jehovah. So he finished the house. And king Solomon made a navy of ships in Ezion-geber, which is beside Eloth, on the shore of the Red Sea, in the land of Edom. And Hiram sent in the navy his servants, shipmen that had knowledge of the sea, with the servants of Solomon. And they came to Ophir, and fetched from thence gold, four hundred and twenty talents, and brought it to king Solomon.
