³² Yarov‘am instituted a festival in the eighth month, on the fifteenth day of the month, similar to the festival held in Y’hudah; he went up to the altar in Beit-El to sacrifice to the calves he had made; and he placed in Beit-El the cohanim he had appointed for the high places. ³³ He went up to the altar which he had set up in Beit-El on the fifteenth day of the eighth month, in the month which he had chosen on his own, and instituted a festival for the people of Isra’el; he went up to the altar to burn incense.
