“King Solomon built Tadmor in the wilderness and all the storage towns which he built in Hamath. He also built Upper Beth-horon and Lower Beth-horon, fortified cities with walls, gates, and bars, and Baalath, as well as all his storage towns, and all the towns for his chariots, and the towns for his cavalry. Whatever King Solomon desired to build in Jerusalem, in Lebanon, and in all the land of his dominion it was done.”
Based on 1 Kings, chapter 9, King Solomon rebuilt towns. This seems to be the continuation of the beginning of this chapter. He built separate towns just for his horses, his chariots, his cavalry, and his own storage facilities. There in 1 Kings, he had the help of the Egyptian Pharaoh, but there is no mention of him here. King Solomon rebuilt the wilderness town of Tadmor in the south as well as Hamath in the north near Syria. He also rebuilt the fortified cities of Upper and Lower Beth-horon in the northwest area of Benjamin. Baalath was a storage city in Dan. In other words, King Solomon built towns and cities all over the place, wherever he wanted or needed a storage town.
