1 Kings 12:32-33 New American Bible (Revised Edition) (NABRE)
32 Jeroboam established a feast in the eighth month on the fifteenth day of the month like the pilgrimage feast in Judah, and he went up to the altar. He did this in Bethel, sacrificing to the calves he had made. He stationed in Bethel the priests of the high places he had built. 33 Jeroboam went up to the altar he built in Bethel on the fifteenth day of the eighth month, the month he arbitrarily chose. He established a feast for the Israelites, and he went up to the altar to burn incense.
