"Go ye and seek of the LORD for me, and the people, and for all Judah; concerning the words of this book that is found. For it is a great wrath of the LORD that is kindled upon us, that our fathers have not hearkened unto the words of this book, to do in all points as it is written therein."

And the king commanded all the people, saying, "Keep the feast of passover unto the LORD your God, as it is written in the book of this covenant."
