'Words of This Book' in the Bible

"Go inquire of Yahweh for me, and for the people, and for all Judah, concerning the words of this book that is found; for great is the wrath of Yahweh that is kindled against us, because our fathers have not listened to the words of this book, to do according to all that which is written concerning us."

He said to me, "See you don't do it! I am a fellow bondservant with you and with your brothers, the prophets, and with those who keep the words of this book. Worship God."
