1 Kings 9:20-22

There were other people in the land who were not Israelites—Amorites, Hittites, Perizzites, Hivites, and Jebusites. They were descendants of people that the Israelites had not destroyed. Solomon forced them to work for him as slaves, as is still true today. But Solomon did not make slaves of the Israelites. They were his soldiers, government leaders, officers, captains, chariot commanders, and drivers.
