2 Chronicles 11:12-22 MSG

12 He installed arms - large shields and spears - in all the forts, making them very strong. So Judah and Benjamin were secure for the time.
13 The priests and Levites from all over Israel came and made themselves available to Rehoboam.
14 The Levites left their pastures and properties and moved to Judah and Jerusalem because Jeroboam and his sons had dismissed them from the priesthood of God
15 and replaced them with his own priests to preside over the worship centers at which he had installed goat and calf demon-idols.
16 Everyone from all the tribes of Israel who determined to seek the God of Israel migrated with the priests and Levites to Jerusalem to worship there, sacrificing to the God of their ancestors.
17 That gave a tremendous boost to the kingdom of Judah. They stuck with Rehoboam son of Solomon for three years, loyal to the ways of David and Solomon for this period.
18 Rehoboam married Mahalath daughter of Jerimoth, David's son, and Abihail daughter of Eliab, Jesse's son.
19 Mahalath bore him Jeush, Shemariah, and Zaham.
20 Then he married Maacah, Absalom's daughter, and she bore him Abijah, Attai, Ziza, and Shelomith.
21 Maacah was Rehoboam's favorite wife; he loved her more than all his other wives and concubines put together (and he had a lot - eighteen wives and sixty concubines who produced twenty-eight sons and sixty daughters!).
22 Rehoboam designated Abijah son of Maacah as the "first son" and leader of the brothers - he intended to make him the next king.
