1 Kings 12:28-30 NLT

28 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. O Israel, these are the gods who brought you out of Egypt!"
29 He placed these calf idols at the southern and northern ends of Israel -- in Bethel and in Dan.
30 This became a great sin, for the people worshiped them, traveling even as far as Dan.
