1 Kings 12:32

³⁰And this thing became a sin; and the people went before one as far as Dan, and left the house of the Lord.

³¹And he made houses on the high places, and made priests of any part of the people, who were not of the sons of Levi.

— 1 Kings 12:32 —

³³and went up to the altar which he made in Bethel to sacrifice to the heifers which he made, and he placed in Bethel the priests of the high places which he had made. And he went up to the altar which he had made, on the fifteenth day in the eighth month, at the feast which he devised out of his own heart; and he made a feast to the children of Israel, and went up to the altar to sacrifice.
