2 Kings 23:21-23

King Josiah then issued this order to all the people: “You must celebrate the Passover to the LORD your God, as required in this Book of the Covenant.” There had not been a Passover celebration like that since the time when the judges ruled in Israel, nor throughout all the years of the kings of Israel and Judah. But in the eighteenth year of King Josiah’s reign, this Passover was celebrated to the LORD in Jerusalem.
