2 Tawarikh 35:18-19

35:18 A Passover like this had not been observed in Israel since the days of Samuel the prophet. None of the kings of Israel had observed a Passover like the one celebrated by Josiah, the priests, the Levites, all the people of Judah and Israel who were there, and the residents of Jerusalem. 35:19 This Passover was observed in the eighteenth year of Josiah’s reign.
