1 Kings 9:21-22

21The Israelites had not been able to remove all of these people, so their descendants remained in the land. So Solomon made them do hard work as his slaves. They are still slaves of the Israelites today.

22But Solomon did not make any of the Israelites do the hard work. Instead, they served him as his soldiers, government officers and army officers. Some of the soldiers drove chariots and some were leaders of the chariot drivers.
