Chronicles II 35:17 In-Context

15 And the sons of Asaph the psalm-singers at their post according to the commands of David, and Asaph, and Aeman, and Idithom, the prophets of the king: also, the chiefs and the porters of the several gates; —it was not for them to stir from the service of the holy things, for their brethren the Levites prepared for them.
16 So all the service of the Lord was duly ordered and prepared in that day, for keeping the passover, and offering the whole-burnt-sacrifices on the altar of the Lord, according to the command of king Josias.
17 And the children of Israel that were present kept the passover at that time, and the feast of unleavened bread seven days.
18 And there was no passover like it in Israel from the days of Samuel the prophet, or any king of Israel: they kept not such a passover as Josias, and the priests, and the Levites, and all Juda and Israel that were present, and the dwellers in Jerusalem, kept to the Lord.
19 In the eighteenth year of the reign of Josias this passover was kept, after all these things that Josias did in the house. And king Josias burnt those who had in them a divining spirit, and the wizards, and the images, and the idols, and the sodomites which were in the land of Juda and in Jerusalem, that he might confirm the words of the law that were written in the book which Chelcias the priest found in the house of the Lord. There was no like him before him, who turned to the Lord with all his heart, and all his soul, and all his strength, according to all the law of Moses, and after him there rose up none like him. Nevertheless the Lord turned not from the anger of his fierce wrath, wherewith the Lord was greatly angry against Juda, for all the provocations wherewith Manasses provoked him: and the Lord said, I will even remove Juda also from my presence, as I have removed Israel, and I have rejected the city which I chose, Jerusalem, and thehouse of which I said, My name shall be there.
