'Festival' in the Bible

So he prepared a large festival for them, and when they had finished eating and drinking, he sent them back to their master, and marauding gangs of Arameans never came into the territory of Israel again.

When Josiah turned around, he saw the tombs there on the hill. So he ordered the bones from the tombs to be brought; he burned them on the altar and defiled it. This fulfilled the Lord's announcement made by the prophet while Jeroboam stood by the altar during a festival. King Josiah turned and saw the grave of the prophet who had foretold this.
