1 Kings 12:26–33

²⁶And Jeroboam said in his heart, “Now the kingdom will turn back to the house of David; ²⁷if this people go up to offer sacrifices in the house of the Lord at Jerusalem, then the heart of this people will turn again to their lord, to Rehoboam king of Judah, and they will kill me and return to Rehoboam king of Judah.” ²⁸So the king took counsel, and made two calves of gold. And he said to the people, “You have gone up to Jerusalem long enough. Behold your gods, O Israel, who brought you up out of the land of Egypt.” ²⁹And he set one in Bethel, and the other he put in Dan. ³⁰And this thing became a sin, for the people went to the one at Bethel and to the other as far as Dan.^{j 31}He also made houses on high places, and appointed priests from among all the people, who were not of the Levites. ³²And Jeroboam appointed a feast on the fifteenth day of the eighth month like the feast that was in Judah, and he offered sacrifices upon the altar; so he did in Bethel, sacrificing to the calves that he had made. And he placed in Bethel the priests of the high places that he had made. ³³He went up to the altar which he had made in Bethel on the fifteenth day in the eighth month, in the month which he had devised of his own heart; and he ordained a feast for the people of Israel, and went up to the altar to burn incense.
