Levites: Degraded from the Levitical office by Jeroboam
Source: Nav
2 Chronicles 11:13–17
Moreover, the priests and Levites from all their districts throughout Israel stood with Rehoboam. / For 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. / And Jeroboam appointed his own priests for the high places and for the goat demons and calf idols he had made.
2 Chronicles 13:9–11
But did you not drive out the priests of the LORD, the sons of Aaron, and the Levites? And did you not make priests for yourselves as do the peoples of other lands? Now whoever comes to consecrate himself with a young bull and seven rams can become a priest of things that are not gods. / But as for us, the LORD is our God. We have not forsaken Him; the priests who minister to the LORD are sons of Aaron, and the Levites attend to their duties. / Every morning and every evening they present burnt offerings and fragrant incense to the LORD. They set out the rows of showbread on the ceremonially clean table, and every evening they light the lamps of the gold lampstand. We are carrying out the requirements of the LORD our God, while you have forsaken Him.
