2 Chronicles 35:17-18

35:17 So the Israelites who were present observed the Passover at that time, as well as the Feast of Unleavened Bread for seven days. 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.
