1 Kings 12:31-33

CAB(i) 31 And he made houses on the high places, and made priests of any part of the people, who were not of the sons of Levi. 32 And Jeroboam appointed a feast in the eighth month, on the fifteenth day of the month, according to the feast in the land of Judah; 33 and 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 dy 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.
