Then Josiah announced that the Passover of the LORD would be celebrated in Jerusalem on the appointed day in early spring. The Passover lambs were slaughtered at twilight of that day.

Josiah also assigned the priests to their duties and encouraged them in their work at the Temple of the LORD.
He issued this order to the Levites, who had been set apart to serve the LORD and were teachers in Israel: "Since the Ark is now in Solomon's Temple and you do not need to carry it back and forth on your shoulders, spend your time serving the LORD your God and his people Israel.
Report for duty according to the family divisions of your ancestors, following the written instructions of King David of Israel and the instructions of his son Solomon.
Then stand in your appointed holy places and help the families assigned to you as they bring their offerings to the Temple.
Slaughter the Passover lambs, purify yourselves, and prepare to help those who come. Follow all the instructions that the LORD gave through Moses."
Then Josiah contributed from his personal property thirty thousand lambs and young goats for the people's Passover offerings, and three thousand bulls.
The king's officials also made willing contributions to the people, priests, and Levites. Hilkiah, Zechariah, and Jehiel, the administrators of God's Temple, gave the priests twenty-six hundred lambs and young goats and three hundred bulls as Passover offerings.
The Levite leaders -- Conaniah and his brothers Shemaiah and Nethanel, and Hashabiah, Jeiel, and Jozabad -- gave five thousand lambs and young goats and five hundred bulls to the Levites for their Passover offerings.
When everything was ready for the Passover celebration, the priests and the Levites took their places, organized by their divisions, according to the king's orders.
The Levites then slaughtered the Passover lambs and presented the blood to the priests, who sprinkled the blood on the altar while the Levites prepared the animals.
They divided the burnt offerings among the people by their family groups, so they could offer them to the LORD according to the instructions recorded in the Book of Moses. They did the same with the bulls.
Then they roasted the Passover lambs as prescribed; and they boiled the holy offerings in pots, kettles, and pans, and brought them out quickly so the people could eat them.
Afterward the Levites prepared a meal for themselves and for the priests, because the priests had been busy from morning till night offering the burnt offerings and the fat portions. The Levites took responsibility for all these preparations.
The musicians, descendants of Asaph, were in their assigned places, following the orders given by David, Asaph, Heman, and Jeduthun, the king's seer. The gatekeepers guarded the gates and did not need to leave their posts of duty, for their meals were brought to them by their fellow Levites.
The entire ceremony for the LORD's Passover was completed that day. All the burnt offerings were sacrificed on the altar of the LORD, as King Josiah had ordered.
All the Israelites present in Jerusalem celebrated Passover and the Festival of Unleavened Bread for seven days.
Never since the time of the prophet Samuel had there been such a Passover. None of the kings of Israel had ever kept a Passover as Josiah did, involving all the priests and Levites, all the people of Jerusalem, and people from all over Judah and Israel.
This Passover celebration took place in the eighteenth year of Josiah's reign.
After Josiah had finished restoring the Temple, King Neco of Egypt led his army up from Egypt to do battle at Carchemish on the Euphrates River, and Josiah and his army marched out to fight him.
But King Neco sent ambassadors to Josiah with this message: "What do you want with me, king of Judah? I have no quarrel with you today! I only want to fight the nation with which I am at war. And God has told me to hurry! Do not interfere with God, who is with me, or he will destroy you."
But Josiah refused to listen to Neco, to whom God had indeed spoken, and he would not turn back. Instead, he led his army into battle on the plain of Megiddo. He laid aside his royal robes so the enemy would not recognize him.
But the enemy archers hit King Josiah with their arrows and wounded him. He cried out to his men, "Take me from the battle, for I am badly wounded!"
So they lifted Josiah out of his chariot and placed him in another chariot. Then they brought him back to Jerusalem, where he died. He was buried there in the royal cemetery. And all Judah and Jerusalem mourned for him.
The prophet Jeremiah composed funeral songs for Josiah, and to this day choirs still sing these sad songs about his death. These songs of sorrow have become a tradition and are recorded in The Book of Laments.
The rest of the events of Josiah's reign and his acts of devotion done according to the written law of the LORD,
from beginning to end, are recorded in The Book of the Kings of Israel and Judah.
