1 Kings 12:29-32

MSB(i) 29 One calf he set up in Bethel, and the other in Dan. 30 And this thing became a sin; the people walked as far as Dan to worship before one of the calves. 31 Jeroboam also built shrines on the high places and appointed from every class of people priests who were not Levites. 32 And Jeroboam ordained a feast on the fifteenth day of the eighth month, like the feast that was in Judah, and he offered sacrifices on the altar; he made this offering in Bethel to sacrifice to the calves he had set up, and he installed priests in Bethel for the high places he had set up.
