14And afterward they made ready for themselves, and for the priests: because the priests the sons of Aaron were busied in offering of burnt offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests the sons of Aaron. 15And the singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the porters waited at every gate; they might not depart from their service; for their brethren the Levites prepared for them. 16So all the service of the LORD was prepared the same day, to keep the passover, and to offer burnt offerings upon the altar of the LORD, according to the commandment of king Josiah. 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 Carchemish by Euphrates: and Josiah went out against him.
