1 Kings 9:15, 22-23

And this is the account of the forced labor that King Solomon drafted to build the house of the LORD and his own house and the Millo and the wall of Jerusalem and Hazor and Megiddo and Gezer

But of the people of Israel Solomon made no slaves. They were the soldiers, they were his officials, his commanders, his captains, his chariot commanders and his horsemen. These were the chief officers who were over Solomon’s work: 550 who had charge of the people who carried on the work.
