1 Kings 12:26-27
26-27But then Jeroboam thought, "It won't be long before the kingdom is reunited under David. As soon as these people resume worship at The Temple of God in Jerusalem, they'll start thinking of Rehoboam king of Judah as their ruler. They'll then kill me and go back to King Rehoboam."
28-30So 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!" He put one calf in Bethel; the other he placed in Dan. This was blatant sin. Think of it—people traveling all the way to Dan to worship a calf!
