1 Kings 12:29, 32

He set the one [golden calf] in Bethel, and the other he put in Dan.

Jeroboam held a feast on the fifteenth day of the eighth month, like the feast which is kept in Judah, and he went up to the altar; he did this in Bethel, sacrificing to the calves which he had made. And he stationed in Bethel the priests of the high places which he had made. [Lev 23:34]
