1 Kings 12:28-31
28 Therefore the king asked advice, made two calves of gold,
and said to the people, “It is too much for you to go up to Jerusalem.
Here are your gods, O Israel, which brought you
up from the land of Egypt!”
29 And he set up one in Bethel, and the other he put in Dan.
30 Now this thing became a sin, for the people went
to worship before the one as far as Dan.
31 He made shrines on the high places,
and made priests from every class of people,
who were not of the sons of Levi.
