2 Chronicles 11:13-17

13Moreover, the priests and Levites from all their districts throughout Israel stood with Rehoboam. 14For the Levites left their pasturelands and their possessions and went to Judah and Jerusalem, because Jeroboam and his sons had rejected them as priests of the LORD. 15And Jeroboam appointed his own priests for the high places and for the goat demons and calf idols he had made.

16Those from every tribe of Israel who had set their hearts to seek the LORD their God followed the Levites to Jerusalem to sacrifice to the LORD, the God of their fathers. 17So they strengthened the kingdom of Judah and supported Rehoboam son of Solomon for three years, because they walked for three years in the way of David and Solomon.
