2 Chronicles 35:16-19

16And all the service of Jehovah was prepared the same day, to hold the passover, and to offer burnt-offerings on the altar of Jehovah according to the commandment of king Josiah.

17And the children of Israel that were present held the passover at that time, and the feast of unleavened bread seven days.

18And there was no passover like to that holden in Israel from the days of Samuel the prophet; neither did all the kings of Israel hold such a passover as Josiah held, and the priests, and the Levites, and all Judah and Israel that were present, and the inhabitants of Jerusalem.

19In the eighteenth year of the reign of Josiah was this passover holden.
