and went up to the altar which he made in Bæthel to sacrifice to the heifers which he made, and he placed in Bæthel 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.
On the fifteenth day of the eighth month, a month of his own choosing, Jeroboam offered sacrifices on the altar he had set up in Bethel. So he ordained a feast for the Israelites, offered sacrifices on the altar, and burned incense.
