2 Chronicles 11:20-22

And after her he took Maachah the daughter of Absalom; which bare him Abijah, and Attai, and Ziza, and Shelomith. And Rehoboam loved Maachah the daughter of Absalom above all his wives and his concubines: (for he took eighteen wives, and threescore concubines; and begat twenty and eight sons, and threescore daughters.) And Rehoboam made Abijah the son of Maachah the chief, to be ruler among his brethren: for he thought to make him king.
