1 Kings 12:28-30 MSG

28 So the king came up with a plan: He made two golden calves. Then he announced, "It's too much trouble for you to go to Jerusalem to worship. Look at these - the gods who brought you out of Egypt!"
29 He put one calf in Bethel; the other he placed in Dan.
30 This was blatant sin. Think of it - people traveling all the way to Dan to worship a calf!
