1 Kings 12:30 akjv — And this thing became a sin: for the people went to worship before the one, even to Dan.

If this people go up to do sacrifice in the house of the LORD at Jerusalem, then shall the heart of this people turn again to their lord, even to Rehoboam king of Judah, and they shall kill me, and go again to Rehoboam king of Judah.

Whereupon the king took counsel, and made two calves of gold, and said to them, It is too much for you to go up to Jerusalem: behold your gods, O Israel, which brought you up out of the land of Egypt.

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

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

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

So he offered on the altar which he had made in Bethel the fifteenth day of the eighth month, even in the month which he had devised of his own heart; and ordained a feast to the children of Israel: and he offered on the altar, and burnt incense.
