2 Chronicles 35:17

14 And after that, they made ready for themselves and for the priests; for the priests, the sons of Aaron, were offering the burned offerings and the fat till night; so the Levites made ready what was needed for themselves and for the priests, the sons of Aaron.

15 And the sons of Asaph, the makers of melody, were in their places, as ordered by David and Asaph and Heman and Jeduthun, the king's seer; and the door-keepers were stationed at every door: there was no need for them to go away from their places, for their brothers the Levites made ready for them.

16 So everything needed for the worship of the Lord was made ready that same day, for the keeping of the Passover and the offering of burned offerings on the altar of the Lord, as King Josiah had given orders.

17 And all the children of Israel who were present kept the Passover and the feast of unleavened bread at that time for seven days.

18 No Passover like it had been kept in Israel from the days of Samuel the prophet; and not one of the kings of Israel had ever kept a Passover like the one kept by Josiah and the priests and the Levites and all those of Judah and Israel who were present, and the people of Jerusalem.

19 In the eighteenth year of the rule of Josiah this Passover was kept.

20 After all this, and after Josiah had put the house in order, Neco, king of Egypt, went up to make war at Carchemish by the river Euphrates; and Josiah went out against him.
