1 Kings 9:21-22

21their children who were left after them in the land, whom the Israelites were unable to completely destroy, from them Solomon levied (conscripted) forced laborers, even to this day (the date of this writing).

22But Solomon did not make slaves of the sons of Israel; for they were men of war (soldiers), his servants, his officers, his captains, his chariot commanders, and his horsemen.
