1 Kings 9:19-22

19all the storage cities that Solomon had, cities for his chariots and cities for his cavalry, and whatever Solomon desired to build in Jerusalem, in Lebanon, and in all the land of his dominion.

20All the people who were left of the Amorites, Hittites, Perizzites, Hivites, and Jebusites, who were not of the children of Israel—

21that is, their descendants who were left in the land after them, whom the children of Israel had not been able to destroy completely—from these Solomon raised forced labor, as it is to this day.

22But of the children of Israel Solomon made no forced laborers, because they were men of war and his servants: his officers, his captains, commanders of his chariots, and his cavalry.
