"He made upper Beth Horon and lower Beth Horon fortified cities with walls and barred gates,"
— 2 Chronicles 8:5, NET Bible
“Also he built Beth–horon the upper, and Beth–horon the nether, fenced cities, with walls, gates, and bars;”
“Also he built Beth-horon the upper, and Beth-horon the nether, fortified cities, with walls, gates, and bars; ”
“Also he built Beth Horon the upper, and Beth Horon the lower, fortified cities, with walls, gates, and bars;”
“And he built Beth-horon the upper, and Beth-horon the nether, walled cities with gates and bars and locks.”
“And of Beth-horon the higher and the lower, walled towns with walls and doorways and locks;”
“Also he built Beth–horon the upper, and Beth–horon the nether, fenced cities, with walls, gates, and bars;”
Solomon rebuilt the cities that Huram had given him and settled Israelites there.
Solomon went to Hamath Zobah and seized it.
He built up Tadmor in the wilderness and all the storage cities he had built in Hamath.
He made upper Beth Horon and lower Beth Horon fortified cities with walls and barred gates,
and built up Baalath, all the storage cities that belonged to him, and all the cities where chariots and horses were kept. He built whatever he wanted in Jerusalem, Lebanon, and throughout his entire kingdom.
Now several non-Israelite peoples were left in the land after the conquest of Joshua, including the Hittites, Amorites, Perizzites, Hivites, and Jebusites.
Their descendants remained in the land(the Israelites were unable to wipe them out). Solomon conscripted them for his work crews and they continue in that role to this very day.
