2 Chronicles 35:16-18

New Catholic Bible

¹⁶ Thus the entire service of the Lord was arranged on that day in order to celebrate the Passover and the Feast of Unleavened Bread for seven days. ¹⁷ The people of Israel who were present on that occasion kept the Passover at that time, as well as the Feast of Unleavened Bread, for seven days.

¹⁸ No Passover like this one had been observed in Israel since the days of the prophet Samuel, nor had any of the kings of Israel ever celebrated a Passover as was kept by Josiah, by the priests and the Levites, by all the people of Judah and Israel who were there, and by the inhabitants of Jerusalem.
