1 Kings 9:23-28

Solomon appointed 550 of them to supervise the people working on his various projects. Solomon moved his wife, Pharaoh’s daughter, from the City of David to the new palace he had built for her. Then he constructed the supporting terraces. Three times each year Solomon presented burnt offerings and peace offerings on the altar he had built for the LORD. He also burned incense to the LORD. And so he finished the work of building the Temple. King Solomon also built a fleet of ships at Ezion-geber, a port near Elath in the land of Edom, along the shore of the Red Sea. Hiram sent experienced crews of sailors to sail the ships with Solomon’s men. They sailed to Ophir and brought back to Solomon some sixteen tons of gold.
