So the king asked for advice and then made two gold calves. He said to the people, "It's too far for you to go all the way up to Jerusalem. Look, Israel! Here are your gods who brought you out from the land of Egypt."
He put one calf in Bethel, and the other he placed in Dan.
This act was sinful. The people went to worship before the one calf at Bethel and before the other one as far as Dan.
