Then Jeroboam instituted a festival in the eighth month, on the fifteenth day of the month, imitating the Festival that is in Judah. He went up to the altar that he built in Bethel, to sacrifice to the calves that he had made. He installed in Bethel the priests of the high places that he made.
So Solomon and all Israel with him celebrated the Festival at that time—a great congregation from the entrance of Hamath to the Wadi of Egypt—before Adonai Eloheinu, seven days and then seven more days—14 days in all.
They also kept the Feast of Sukkot as it is written and offered the prescribed number of daily burnt offerings according to the requirement for each day.
