2 Chronicles 8:1-10

Now it came about at the end of the twenty years in which Solomon had built the house of the LORD and his own house that he built the cities which Huram had given to him, and settled the sons of Israel there. Then Solomon went to Hamath-zobah and captured it. He built Tadmor in the wilderness and all the storage cities which he had built in Hamath. He also built upper Beth-horon and lower Beth-horon, fortified cities with walls, gates and bars; and Baalath and all the storage cities that Solomon had, and all the cities for his chariots and cities for his horsemen, and all that it pleased Solomon to build in Jerusalem, in Lebanon, and in all the land under his rule. All of the people who were left of the Hittites, the Amorites, the Perizzites, the Hivites and the Jebusites, who were not of Israel, namely, from their descendants who were left after them in the land whom the sons of Israel had not destroyed, them Solomon raised as forced laborers to this day. But Solomon did not make slaves for his work from the sons of Israel; they were men of war, his chief captains and commanders of his chariots and his horsemen. These were the chief officers of King Solomon, two hundred and fifty who ruled over the people.
