1 Kings
Chapters 12:30-33
Revised Version 1885
30And this thing became a sin: for the people went to worship before the one, even unto Dan.
31And he made houses of high places, and made priests from among all 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 went up unto the altar; so did he in Beth-el, sacrificing unto the calves that he had made: and he placed in Beth-el the priests of the high places which he had made.
33And he went up unto the altar which he had made in Beth-el on the fifteenth day in the eighth month, even in the month which he had devised of his own heart: and he ordained a feast for the children of Israel, and went up unto the altar, to burn incense.
