1 Kings 12:31-33

Revised Geneva Translation

³¹ Also, he made a house of high places, and made priests of the lowest of the people, who were not of the sons of Levi.

³² And Jeroboam made a feast on the fifteenth day of the eighth month, like the Feast that is in Judah, and offered on the altar. So he did in Bethel, and offered to the calves that he had made. And he placed the priests of the high places which he had made in Bethel.

³³ And he offered upon the altar, which he had made in Bethel, on the fifteenth day of the eighth month, (in the month which he had forged of his own heart) and made a solemn feast to the children of Israel. And he went up to the altar, to burn incense.
