II Kings 23:21-23

²¹Then the king commanded all the people saying, “Celebrate the Passover to the Lord your God as it is written in this book of the covenant.” ²²Surely such a Passover had not been celebrated from the days of the judges who judged Israel, nor in all the days of the kings of Israel and of the kings of Judah. ²³But in the eighteenth year of King Josiah, this Passover was observed to the Lord in Jerusalem.
