1 Kings 12:28-32

28So the king sought advice. Then he made two golden calves, and he said to the people, “Going to Jerusalem is too difficult for you. Israel, here are your gods who brought you up from the land of Egypt.”

29He set up one in Bethel, and put the other in Dan.

30This led to sin; the people walked in procession before one of the calves all the way to Dan.

31Jeroboam also made shrines on the high places and made priests from the ranks of the people who were not Levites.

32Jeroboam made a festival in the eighth month on the fifteenth day of the month, like the festival in Judah. He offered sacrifices on the altar; he made this offering in Bethel to sacrifice to the calves he had made. He also stationed the priests in Bethel for the high places he had made.
