Melachim Alef 12:29-31

Orthodox Jewish Bible

²⁹ He set the one in Beit-El, the other put he in Dan.

³⁰ And this thing became chattat (sin); for the people went to worship before the one, even as far as Dan.

³¹ And he made a bais for the [idolatrous] high places, and made kohanim of the lowest of the people, which were not of the Bnei Levi.
