Second Chronicles 8 describes Solomon's building activities after construction of the Temple and royal palace. The Chronicler states that Solomon built Tadmor in the wilderness together with store cities in Hamath.
The traditional identification of Tadmor with Palmyra would place Solomon's activity far northeast of Israel along an important desert trade route.
The parallel passage in 1 Kings 9:18 presents a textual difficulty. The Hebrew consonantal text is commonly read Tamar, a name associated elsewhere with southern territory, while a traditional marginal reading gives Tadmor.
Consequently, the biblical connection between Solomon and Palmyra should be presented as traditional and possible rather than treated as an archaeologically demonstrated fact.
