1 Kings 9:19-24

¹⁹and all the storage cities which Solomon had, that is, the cities for his chariots and the cities for his horsemen, and everything that it pleased Solomon to build in Jerusalem, in Lebanon, and in all the land under his rule. ²⁰As for all the people who were left of the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites, who were not of the sons of Israel, ²¹their descendants who were left after them in the land, whom the sons of Israel were unable to completely eliminate, from them Solomon conscripted forced laborers, as they are to this day. ²²But Solomon did not make slaves of the sons of Israel; for they were men of war, his servants, his commanders, his charioteers, his chariot commanders, and his horsemen.

²³These were the chief officers who were in charge of Solomon’s work, 550, who ruled over the people doing the work.

²⁴As soon as Pharaoh’s daughter came up from the city of David to her house which Solomon had built for her, he then built the Millo.
