1 Kings 12:26-32

Jeroboam thought to himself, “Unless I am careful, the kingdom will return to the dynasty of David. When these people go to Jerusalem to offer sacrifices at the Temple of the LORD, they will again give their allegiance to King Rehoboam of Judah. They will kill me and make him their king instead.” So on the advice of his counselors, the king made two gold calves. He said to the people, “It is too much trouble for you to worship in Jerusalem. Look, Israel, these are the gods who brought you out of Egypt!” He placed these calf idols in Bethel and in Dan—at either end of his kingdom. But this became a great sin, for the people worshiped the idols, traveling as far north as Dan to worship the one there. Jeroboam also erected buildings at the pagan shrines and ordained priests from the common people—those who were not from the priestly tribe of Levi. And Jeroboam instituted a religious festival in Bethel, held on the fifteenth day of the eighth month, in imitation of the annual Festival of Shelters in Judah. There at Bethel he himself offered sacrifices to the calves he had made, and he appointed priests for the pagan shrines he had made.
