2 Chronicles 35:19 KJV

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

18And there was no passover like to that kept in Israel from the days of Samuel the prophet; neither did all the kings of Israel keep such a passover as Josiah kept, 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 kept.

20After all this, when Josiah had prepared the temple, Necho king of Egypt came up to fight against Charchemish by Euphrates: and Josiah went out against him.

21But he sent ambassadors to him, saying, What have I to do with thee, thou king of Judah? I come not against thee this day, but against the house wherewith I have war: for God commanded me to make haste: forbear thee from meddling with God, who is with me, that he destroy thee not.
