1 Kings 9:19-22

19and all the store-cities that Solomon had, and the cities for his chariots, and the cities for his horsemen, and that which Solomon desired to build for his pleasure in Jerusalem, and in Lebanon, and in all the land of his dominion. 20As for all the people that were left of the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites, who were not of the children of Israel; 21their children that were left after them in the land, whom the children of Israel were not able utterly to destroy, of them did Solomon raise a levy of bondservants unto this day. 22But of the children of Israel did Solomon make no bondservants; but they were the men of war, and his servants, and his princes, and his captains, and rulers of his chariots and of his horsemen.
