2 Chronicles 11:9

And Adoraim, and Lachish, and Azekah,

Adoraim, Lachish, and Azekah were among the defensive cities in Judah that Rehoboam built and fortified. He supplied those cities and made them strong. Yet the fortifications themselves were not the source of Judah's prosperity during those early years. The kingdom was made strong because the people recognized God as supreme ruler and sought Him.
