1 Kings 9:24

their children who were left after them in the land, whom the children of Israel were not able utterly to destroy—of them Solomon raised a levy of bondservants to this day.

But of the children of Israel Solomon made no bondservants; but they were the men of war, his servants, his princes, his captains, and rulers of his chariots and of his horsemen.

These were the five hundred fifty chief officers who were over Solomon’s work, who ruled over the people who labored in the work.

Solomon offered burnt offerings and peace offerings on the altar which he built to the LORD three times per year, burning incense with them on the altar that was before the LORD. So he finished the house.

King Solomon made a fleet of ships in Ezion Geber, which is beside Eloth, on the shore of the Red Sea, in the land of Edom.

Hiram sent in the fleet his servants, sailors who had knowledge of the sea, with the servants of Solomon.
