1 Kings 12:30 KJV

28Whereupon 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.

29And he set the one in Bethel, and the other put he in Dan.

30And this thing became a sin: for the people went to worship before the one, even unto Dan.

31And he made an house of high places, and made priests of the lowest of the people, which were not of the sons of Levi.

32And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah, and he offered upon the altar. So did he in Bethel, sacrificing unto the calves that he had made: and he placed in Bethel the priests of the high places which he had made.
