1 Kings 9:20
“And all the people that were left of the Amorites, Hittites, Perizzites, Hivites, and Jebusites, which were not of the children of Israel,”
And Baalath, and Tadmor in the wilderness, in the land,
And all the cities of store that Solomon had, and cities for his chariots, and cities for his horsemen, and that which Solomon desired to build in Jerusalem, and in Lebanon, and in all the land of his dominion.
And all the people that were left of the Amorites, Hittites, Perizzites, Hivites, and Jebusites, which were not of the children of Israel,
Their children that were left after them in the land, whom the children of Israel also were not able utterly to destroy, upon those did Solomon levy a tribute of bondservice unto this day.
But of the children of Israel did Solomon make no bondmen: but they were men of war, and his servants, and his princes, and his captains, and rulers of his chariots, and his horsemen.
