2 Chronicles 11:21-22

Maacah, the daughter of Absalom, was dearer to Rehoboam than all his wives and his servant-wives: (for he had eighteen wives and sixty servant-wives, and was the father of twenty-eight sons and sixty daughters.) Rehoboam made Abijah, the son of Maacah, chief and ruler among his brothers, for it was his purpose to make him king.
