2 Chronicles 11:12-17

12And in each city he put [large] shields and spears, and made them very strong. So he held Judah and Benjamin.

13Further, the priests and the Levites who were in all Israel took their stand with Rehoboam from all their districts.

14For the Levites left their pasture lands and their property and came to Judah and Jerusalem, because Jeroboam and his sons had excluded them from serving as priests to the Lord.

15Jeroboam appointed his own priests for the high places, for the satyrs (goat demons) and calves (idols) which he had made.

16Those from all the tribes of Israel who set their hearts on seeking the Lord God of Israel followed them to Jerusalem, to sacrifice to the Lord God of their fathers.

17So they strengthened the kingdom of Judah and supported Rehoboam the son of Solomon for three years; for they walked in the way of David and Solomon for three years.
