1 Kings 9:21-22

21These were descendants of the nations whom the people of Israel had not completely destroyed. So Solomon conscripted them as slaves, and they serve as forced laborers to this day.

22But Solomon did not conscript any of the Israelites for forced labor. Instead, he assigned them to serve as fighting men, government officials, officers and captains in his army, commanders of his chariots, and charioteers.
