The king ordered all the people, “Observe the Passover of the LORD your God, as prescribed in this scroll of the covenant.” He issued this edict because a Passover like this had not been observed since the days of the judges; it was neglected for the entire period of the kings of Israel and Judah. But in the eighteenth year of King Josiah’s reign, such a Passover of the LORD was observed in Jerusalem. - 2 Kings 23, NET
