2 Chronicles 13:9

And he made houses on high places, and made priests from among all the people who were not of the sons of Levi.

Now the rest of the acts of Jeroboam, how he made war and how he reigned, behold, they are written in the Book of the Chronicles of the Kings of Israel.

Now there was war between Rehoboam and Jeroboam all the days of his life.

Now the rest of the acts of Abijam and all that he did, are they not written in the Book of the Chronicles of the Kings of Judah? And there was war between Abijam and Jeroboam.

For the Levites left their pasture lands and their possession of land and went to Judah and Jerusalem, for Jeroboam and his sons had rejected them from ministering as priests to Yahweh—

Then Hezekiah answered and said, “Now that you have become ordained to Yahweh, approach and bring sacrifices and thank offerings to the house of Yahweh.” And the assembly brought sacrifices and thank offerings, and all those who were willing of heart brought burnt offerings.

However at that time, when you did not know God, you were slaves to those which by nature are no gods.
