2 Chronicles 11:5-12

Rehoboam remained in Jerusalem and fortified various towns for the defense of Judah. He built up Bethlehem, Etam, Tekoa, Beth-zur, Soco, Adullam, Gath, Mareshah, Ziph, Adoraim, Lachish, Azekah, Zorah, Aijalon, and Hebron. These became the fortified towns of Judah and Benjamin. Rehoboam strengthened their defenses and stationed commanders in them, and he stored supplies of food, olive oil, and wine. He also put shields and spears in these towns as a further safety measure. So only Judah and Benjamin remained under his control.
