2 Chronicles 35:16-19

So all the service of the LORD was prepared that day, to keep the Passover and to offer burnt offerings on the altar of the LORD, according to the command of King Josiah. And the people of Israel who were present kept the Passover at that time, and the Feast of Unleavened Bread seven days. No Passover like it had been kept in Israel since the days of Samuel the prophet. None of the kings of Israel had kept such a Passover as was kept by Josiah, and the priests and the Levites, and all Judah and Israel who were present, and the inhabitants of Jerusalem. In the eighteenth year of the reign of Josiah this Passover was kept.
