2 Chronicles 35:20

16So all the service of the LORD was prepared the same day, to keep the Passover, and to offer burnt offerings on the LORD’s altar, according to the commandment of King Josiah.

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

18There was no Passover like that kept in Israel from the days of Samuel the prophet, nor did any of the kings of Israel keep such a Passover as Josiah kept—with the priests, the Levites, and all Judah and Israel who were present, and the inhabitants of Jerusalem.

19This Passover was kept in the eighteenth year of the reign of Josiah.

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

21But he sent ambassadors to him, saying, “What have I to do with you, you king of Judah? I come not against you today, but against the house with which I have war. God has commanded me to make haste. Beware that it is God who is with me, that he not destroy you.”

22Nevertheless Josiah would not turn his face from him, but disguised himself, that he might fight with him, and didn’t listen to the words of Neco from the mouth of God, and came to fight in the valley of Megiddo.

23The archers shot at King Josiah; and the king said to his servants, “Take me away, because I am seriously wounded!”

24So his servants took him out of the chariot, and put him in the second chariot that he had, and brought him to Jerusalem; and he died, and was buried in the tombs of his fathers. All Judah and Jerusalem mourned for Josiah.
