And the king commanded all the people, saying , Keep the passover unto the LORD your God, as it is written in the book of this covenant.
Surely there was not holden such a passover from the days of the judges that judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah;
But in the eighteenth year of king Josiah, wherein this passover was holden to the LORD in Jerusalem.
Moreover the workers with familiar spirits, and the wizards, and the images, and the idols, and all the abominations that were spied in the land of Judah and in Jerusalem, did Josiah put away , that he might perform the words of the law which were written in the book that Hilkiah the priest found in the house of the LORD.
