1 Kings 12:28-30 TMBA

28 Whereupon the king took counsel and made two calves of gold, and said unto them, "It is too much for you to go up to Jerusalem. Behold thy gods, O Israel, which brought thee up out of the land of Egypt!"
29 And he set the one in Bethel, and the other put he in Dan.
30 And this thing became a sin, for the people went to worship before the one, even unto Dan.
